Each of these acts as a voltage divider. While old analog synthesizers had wires poking out all over the place. Decorate it to look like a piano keyboard. Think about an enclosure for the keyboard. Prepare a small piece of cardboard that can be cut out to accommodate your buttons. Connect this junction to ground with a kilohm resistor.

Connect the first one at r I FO directly to power. Label the keys. Connect the second. To see the values. The index refers to the order in which the items appear when the array is created.

IT ntr R D Use an if. Use the information from the serial monitor to adjust as necessary. E and F Hz. After the equals sign. They are a convenient tool for you to quickly and efficiently access information. To read or change the elements of the array. To do this.. IT ntr R D Hz. The values included in the example program are Fo OT ballpark figures for these resistor sizes. Because each switch has a different resistor value connecting it to power.

Begin serial communication In your setup. The first item in the array is item 0. To declare an array. As all resistors have some N tolerance for error.. Create an array of Set up an array of four notes using the frequencies listed above.

The to the analog value program references the array to determine what frequency. If the value of A0 matches one of your if statements,. IT ntr R D you can tell the Arduino to play a tone.

Fo OT idea to have a small range of values to check against. If you press the first button, notes[0] will play. If you press the second, notes[1] will play, and if you press the third, notes[2] will play.

This is when arrays become really handy. To stop playing notes when there is no button being pressed, call the noTone function, providing the pin number to stop playing sound on. If your resistors are close in value to the values in the example USE IT program, you should hear some sounds from the piezo when you press the buttons. If not, check the serial monitor to make sure each of the buttons is in a range that corresponds to the notes in the if Press multiple buttons at the same time, and see what sort of values you get in the serial monitor.

Use these new values to 20 hys IBU. You can find frequencies of musical notes on this page: If you replace the switches and resistor ladder with analog sensors, can you use the N. You could use the value to change the duration of a note or, like in the Theremin Project, create a sliding scale of sounds. The tone function is fun for generating sounds, but it does have a few limi- tations. It can only create square waves, not smooth sine waves or triangles. As you saw in Fig. As you start your band, keep some things in mind: By comparing the current millis to a specific value.

An int integer is a bit number. Typically they have a small cavity inside the housing that has a metal. When the Arduino calls delay. What makes tilt switches unique is that they detect orientation.

You used it previously in Project 6 when you created a timer for calibration. It keeps track of the time your Arduino has been running in milliseconds. This allows you to 20 hys IBU count even higher. This is handy. If you wanted to do something every 10 seconds. Up to now.

The long datatype holds a bit number between t in Those may be some large numbers. When a datatype is called unsigned. Delays are also not very helpful for keeping track of time. The millis function helps to solve these problems. An unsigned long can count up to 4.

When tilted in the proper way. Try building a stand with some cardboard or styrofoam and power the Arduino with a battery to make a portable version. Tilt switches are great.

You can create a cover with some nu- meric indicators alongside the lights. Connect the junction where they IT ntr R D meet to digital pin 8.

They are also significantly more expensive. Accelerometers are another type of tilt sensor. If you want the delay between lights to be longer or shorter.

If Set the direction of your In your setup. Create a variable named led. This will be the name of the pin your tilt switch is on. Subtract the currentTime from the the previous loop previousTime and check to see if it is greater than the interval IT ntr R D variable.

To start. This will be be a long datatype. Start out with pin 2. In 10 minutes the time between each LED turning on This will be used to count which LED is the next one to be turned on.

Reset the variables to their With an if statement. The next time you pass the time interval. Read the switch value into the switchState variable.

At the end of an hour. Set the current state to the At the end of the loop. When 20 hys IBU you flip the circuit over. After 10 minutes have passed. If they are different.

Every 10 minutes after that. Because the numbers it generates are larger than what you can store in an int. Can you figure out how you can use the switch- State variable to indicate what direction the lights should go? The led variable can be checked to see if all the lights are on.

Can t in you think of a way to get your attention when the hour is up? Some motors require a higher voltage as well. This field causes the shaft the part that sticks out of the N housing to spin around. Induction is a process by which a changing IT ntr R D electrical current in a wire can generate a changing magnetic field around the wire.

There are many differ- t in ent kinds. Transistors are components that allow you to control high current and high voltage g power sources from the low current output of the Arduino.

Make: Basic Arduino Projects

This way. Moving things takes a lot of energy. Controlling motors with an Arduino is more complicated than just controlling LEDs for a couple of reasons. Motors typically require more current than the Arduino can provide. The Arduino can only provide 40 milliamps mA from its digital pins. To start moving. This reverse voltage. Try attaching an LED to the two leads of your motor.

If nothing happens. For this reason. The diode will only allow electric- Fo OT ity to flow in one direction. Look at the component so that the metal tab is facing away from you.

A change in voltage on the gate makes a connection between the other two pins. This pin is called the drain. Connect the anode of the diode to the ground of the motor and the cathode of the diode to the power g in of the motor. Notice that the diode has a stripe on one end. N They allow current to flow from anode to cathode. The diode will help prevent any back-voltage generated by lC N 12 ica TIO om the motor from going back into your circuit.

This may seem backwards. That end is the negative end. The other end is the positive end. The diode is a polarized component. Connect ground from N the battery to ground of your Arduino on the breadboard with a jumper. This pin is called the gate. There are many kinds of diodes. Connect the source to ground. When the Arduino ac- tivates the transistor by supplying voltage to the gate. Connect digital pin 9 to the left pin on the transistor. The last component to be added is the diode.

Plug Fo OT the 9V battery snap into your breadboard. Connect one end of the motor to the middle pin of the transistor. When LOW. If you vary the voltage. N Read the input. First of all. When HIGH. If it is not pressed. If the switch is pressed.

Check the state of the switch- output high if pressed Pin with digitalRead. Using IT ntr R D your patterns on your spinner. N 6 pinMode switchPin. Power your Arduino over USB. Plug a 9V battery to 20 hys IBU your battery snap. Attach the die-cut paper pattern to a t pu lC N CD as shown in step 3. When you press the switch on the breadboard. Allow to try before proceeding. Experiment t pu lC N with different patterns on the outside to create visual effects.

Use a drop of glue to keep the CD from coming off. They are typically cylinders with slits cut in the side. When the cylinder spins and you look through the slits. To make this system even more advanced. ICs are components that hold large circuits in a tiny package. To build the circuit inside the H-bridge you would probably need another N breadboard. Zoetropes create the illusion of motion from a group of still images that have small changes in them.

Before the internet. These can help simplify IT ntr R D more complex circuits by placing them in an easily replaceable component. In the Motorized Pinwheel Project you got a motor to spin in one direction. H-bridges N Time: The slits help keep the images from becoming a big blur.

If you g were to take power and ground on the motor and flip their orientation. Different ICs have different numbers of pins. Connect pin 7 to digital pin 2.

This is the enable pin on the H-bridge. Connect pin 1 of the H-bridge to digital pin 9 on the Arduino. Add a 10Kohm pull-down resistor in series with ground on the output pin of both switches. You will use this pin to PWM the H-bridge. Attach the center pin to analog N input 0 on the Arduino.

When it receives 5V. Pins 4 and 5 both go to ground. This will be used to control the speed of the motor. N only ground should be connected between the two. These two int pins will switch on and off depending on the signals you send pu lC N 12 ica TIO om to pins 2 and 7. Wire 5V to one Fo OT side and ground to the other.

These are the pins you will use to communicate with the H-bridge. They must be separate. Create variables for motor motorDirection keeps track of which direction the motor is control spinning.

Declare the digital pins as In setup. Use variables to hold the values from your inputs. Store at r I FO the values in their respective variables. IT ntr R D Read the values of the direction switch and potentiometer. If it is different. Change the pins to turn The motorDirection variable determines which direction the the motor in the proper motor is turning.

If the direction switch gets pressed. To set the direction. If motorEnabled is g 0. When motorDirection changes. PWM the motor if it is If the motorEnabled variable is 1. If it is LOW. There are only 2 ways for the motor to spin. Attach the battery to the g in connector. Add a drop of glue to Use the tabs to close the cutout. If you turn the potentiometer. The zoetrope and images provided in the kit are only your starting point: Fo OT try experimenting with your own animations.

Hold your project 12 ica TIO om up. N To do this. Identify one fixed point in it. Once the CD is se- t pu lC N curely attached to the shaft of the motor. If it is going too fast or too slow. Try to gradually return to the original image so that you can play the animation in a continuous loop. Insert the strip of paper with the images inside the zoetrope. Using the analog input to time the flashes of the LED. POV describes the illusion of motion that is created when our t pu lC N eyes observe still images with minor variations in rapid succession.

This could take some fiddling with the knobs. This will Fo OT make it easier to show off your work to everyone. Hook up an LED and resistor to one of your free digital output pins. Also add a sec- ond potentiometer. N With a little work. Position the light so it shines on the images. These pins are used for power and communication. LCD displays. You ask a question to the all-knowing ball.

There are a large number of connections on the board. The one in your kit has 16 columns and 2 rows. The LCD can be used to display alphanumeric characters. The tilt switch in your kit will help replicate the motion of shaking the ball for answers.

The answers will be predetermined. In a schematic. This is a little confusing to newcomers until you get used to it. This pin enables writing to the LCD. RS on the LCD connects to pin The data pins D0-D7 are used to send charac- ter data to the screen. Attach the other side to ground through a kilohm resis- at r I FO tor.

These are the data pins that tell the screen what g in character to display. This places the screen in write mode. In order to write to the next line. Store that number in your reply variable. Create a constant to hold the pin of N the switch pin. The print function writes to the LCD screen. If it is different than it was before. The coordinates of the first column on the second line are 0. The cursor is automatically at the beginning of the top line.

Start the LCD library. Print your first line Set up the switch pin as an input with pinMode in your setup. Use the function lcd. Whenever the statement N random 8 is called. When it hits break. This also moves the cursor back to location 0. Four of the responses will be positive. After the lcd. Each of these different pieces N of code is called a case. Inside the case statements. It tells the Arduino where the end of the case is. IT ntr R D 22 lcd.

The glass only allows certain kinds of light to pass through. Once you have a handle on how it works. To find out more about how the LiquidCrystal library works. It will adjust the contrast 12 ica TIO om of the screen. Try getting text to scroll. When the liquid between the glass is charged. Make sure when you add additional switch cases. You can also try adding more responses. You should get an answer to your IT ntr R D question. This new state runs in a different direction than the polarized glass.

With a switch. LCDs work by changing the electrical properties of a liquid sandwiched between polarized glass. If it is in 20 hys IBU the right range. The piezo you used for playing back sounds in the theremin and keyboard pro- jects can also be used as an input device. In this case.

In code you can track the number of knocks and see if they match your settings. Functions can take arguments and return values. When plugged into 5V. Writing your own function helps save time programming by reusing lC N 12 ica TIO om code instead of writing it out many times. Some LEDs will give you status: Using this informa- tion you can check to see if a number of knocks fall in an acceptable range. A switch will let you lock the motor in place. When the piezo is pressed flat against a solid surface that can vibrate.

N Fo OT Fig. Attach one Fo OT wire to power. Through their respective resistors. Lower resistor values will make the piezo less sensitive to vibrations. Place a 1-megohm resistor between the ground and the other wire. Wire the other end of the piezo to Analog Pin 0 on your Arduino.

Connect the red wire to power. Place a uF electrolytic capacitor across power and ground to smooth out any irregularities in voltage. Variables for lock state and The locked variable will let you know if the lock is enganged or number of knocks not. The last global variable will hold the number of valid knocks you have received. A boolean is a data type that can only be true 1 or false 0. Setting the direction of the In your setup. If it N is locked. You should start with the mechanism unlocked.

Fo OT This will determine what happens in the rest of the program. Move the servo into the lock position. If it N is going to return a value. Wait for a few milliseconds to let it start moving.

Declare the function as type boolean. After checking your function. If this is true. Checking the knock sensor If the locked variable is true. N Add a delay so the lock has plenty of time to move into place. Counting only valid knocks The next statement checks to see if you have fewer than three valid knocks. Print out a status message to the serial monitor. Unlock Check to see if you have three or more valid knocks.

If it is not going to return a value. If these are both true. Fo OT 34 delay You should see the green LED turn on. At this N point value will be set to whatever knockVal is. N Try knocking soft and hard to see what sort of intensity knock triggers your function. You use the return command. Indicating invalid knock. If value is either too quiet or too loud. Blink the yellow LED once and print the value of the knock to the serial monitor.

Check to see if value is greater than your quiet knock. Function returns true To let the main program know what the outcome of the comparison is. Close up your function with one more bracket.

When you solder something. Place the servo in the box so that the arm can move in and out of the holes when closed.

Soldering is a process of joining two or more metal components together with an adhesive that is melted between the joint. You can find a detailed explanation of that example here: N You may need to rearrange your breadboard and Arduino. This de- g in pends on a number of different variables. See arduino. Piezo elements can be used as inputs when wired up as voltage dividers with a high value resistor.

You can look for complex patterns of N knocks based on the amount of vibration and timing together. There are a number of examples online that talk about how to do this. IT ntr R D You can start to make a more complex example by creating a timer with millis. Over t pu lC N time. Designing a function is an easy way to write code that can be reused for specific tasks.

The library checks two pins on your Arduino one is a sender. Preparing the library The most recent version of the CapacitiveSensor library is here: In the folder. Capacitance is a measure of how much electrical charge something can store. These pins will be connected to a metal object like aluminum foil. Download the file to your computer and unzip it. The library you added included an example project. As you get closer to the object.

Place the CapacitiveSensor folder you g unzipped in this folder and restart the Arduino software. This library allows you to measure the capacitance of your body. Capacitance can be measured through non-conductive materials like wood and plastic. Ping pong balls.

Connect the two pins with a 1-megahom resistor. In the same row as pin 2. Digital pin 4 supplies the current to the sensor. Just like with other LED projects. Increas- ing the surface area of the sensor with a larger conductive surface will make it more sensitve. This at r I FO will become your touch sensor. You could g make a base for the lamp out of cardboard. You can hide the sensor behind something solid and it will still work.

If you read only a few samples. N Set up the threshold Set up a variable for the sensing threshold at which the lamp will turn on.

If you take too many samples. The library returns the sensor value using a com- mand called CapacitiveSensor that takes an argument identifying the number of samples you want to read.

When you use this library. IT ntr R D Create a named instance of the library.

Print the sensor value to the serial monitor.. Sensing touch In the loop function. If it is. In the setup function. Then define the pin your LED will be on. Upload N the sketch with the new value. Once installed. Can you use this to get other interactions with the LED? What about multiple sensors for fading the light brighter and darker? If you place a different value resistor between pins 2 and 4 it will change the sensitivity. The light should come on reliably when you touch the wire.

You probably noticed that the values from the sensor changed depending on how much of your finger was touching the conductor. Is this useful for your interface? Press gently on the bare wire you have exposed from 20 hys IBU your breadboard.

The number should increase. Try pressing more firmly and see if it changes. When communicating serially. These will help you to familiarize N yourself with Processing before you start writing software to communicate with your Arduino. When you program your Arduino. N Processing Time: You can use this connection to send data back and forth to other applications. Serial communication means that the two computers. IT ntr R D Before getting started with the project. That number. Processing is based on Java.

This limits the values that the Arduino can send. Processing will then read the bytes Fo OT out of the buffer. When you meet someone. With software. When using serial communication between devices and programs. As the program reads information from the buffer. Connect the middle leg to analogIn pin 0. Upload the program to the Arduino then set it aside while you write your Processing sketch.

Import the serial library. Let the ADC stabilize After sending the byte. In setup. Open a new Processing sketch. With the size function. Loading the image To load the Arduino image into the sketch.

The parameters it expects are Fo OT which application it will be speaking to. If you use this in conjunction with the t in Serial. Printing available serial Processing has the ability to print out status messages using the g ports println command.

If you use logo. The logo is a. This is similar to the color mixing you did in Project 4. When you supply the URL of an image. N Setting the color mode You can change the way Processing works with color information. Processing will download it when you run the program. When you use Serial. Programs like Processing can N understand these raw bytes. If there are bytes there. It background and displaying takes three arguments. The myPort. The Serial. IT ntr R D list contains an array of all the attached serial devices.

You should see a number of charac- t in ters as you twist the knob. Connect your Arduino and open the serial monitor. Use the variable bgcolor as the hue value.

ASCII is information encoded to represent text in computers. Reading Arduino data from Check if there is information from the Arduino. The at r I FO argument should look familiar. You need to tell image what to draw. Setting the image The function background sets the color of the window. The first argument is the hue.

Technical Details

For Windows. Look at the Pro- t pu lC N cessing output window. The number in front of it is the Serial. You should see a list similar to the 12 ica TIO om figure below. Those numbers correspond to the raw bytes you are sending from the Arduino. You should also see values printing out in the Processing window.

On Linux. Find something you find interesting to control the color. There are several serial communication examples in both the Pro- cessing and Arduino IDEs that will help you explore further. Serial communication enables the Arduino to talk with programs on a computer.

Processing is an open source programming environment that the Arduino IDE is based upon. Most electronic devices have a control panel with buttons. While the Arduino can control a lot of things. If you wanted to record and play back recorded sound. IT ntr R D When the internal switch is closed. Controlling recorded sound is a good example.

The switch is connected to two of the output pins 4 and 5 of the optocoupler. Perhaps you want to control a television or a music player. For more information on soldering. If you are not soldering and using tape.

Once you know which fork is ground. Flip the circuit board over and find the tabs that hold the button in place. This method. If you are soldering these wires. Gently bend the tabs back and remove the but- ton from the board. You need to do this with the device turned on. Make sure neither wire connects to the other fork. A small metal disc inside the pushbutton connects these two forks when you press the button.

Connect N the side of the switch that is grounded to pin 4 of the optocou- pler. Connect pin 2 of the optocou- at r I FO pler to ground. To control the switch. This pattern is typical of many electronic devices with pushbuttons. You will be closing the switch with the optocoupler. Connect the other fork to pin 5 of the optocoupler.

Your recording should start to play. N If you trigger the switch while a sound is playing. Wait for a little while Wait for 21 seconds for the whole message to play back before starting the loop again. Attach the battery to the sound recorder. Then the optoPin becomes LOW. Use your voice. How can you take advantage of this to create unique sequences of sounds?

The two circuits are electrically separated from each other inside the component. There are other ICs that support this one with communication and power.

How could you t in incorporate the inputs from earlier projects to trigger these sounds? What other pu lC N 12 ica TIO om battery powered things do you have around the house that need an Arduino to con- trol them?

This technique of controlling an electronic device with an optocoupler by 20 hys IBU connecting to the two sides of a switch can be used in many other devices.

I can't understand, If the video were released under CC licence why the Starter kit book wasn't? Maybe they could release it and it's source formatting code if it's written using LaTeX or something similar under a public repository with a free and open licence, so everybody can correct errors and improve it.

It would be a great advantage for us and for the company too, because they could include a new version of the book with the starter kit. We [1] have just purchased twelve Genuino Starter Kits, which we want to use in educational courses for kids here in Herakilon, Greece and the version that we received has been released under CC-By-SA.

Any ideas where to start?
