I need to control a light tracker by means of a digital PID with arduino. The circuit is simple and consists of a micro servo motor and a photoresistor but, I have no knowledge of the Arduino PID library. What has that got to do with Arduino Mega R3 pinouts photo? Please post technical questions on the forum, not by personal message. More info: MarekBujko Newbie Posts: Where are 4 Input Captures marked?

The Mega board has a number of facilities for communicating with a computer, another board, or other microcontrollers. An ATmega16U2 ATmega 8U2 on the revision 1 and revision 2 boards on the board channels one of these over USB and provides a virtual com port to software on the computer Windows machines will need a. The Arduino Software IDE includes a serial monitor which allows simple textual data to be sent to and from the board.

The maximum length and width of the Mega PCB are 4 and 2. Three screw holes allow the board to be attached to a surface or case. Note that the distance between digital pins 7 and 8 is mil 0.

The Mega is designed to be compatible with most shields designed for the Uno and the older Diecimila or Duemilanove Arduino boards. Furthermore, the main UART serial port is located on the same pins 0 and 1 , as are external interrupts 0 and 1 pins 2 and 3 respectively.

Rather then requiring a physical press of the reset button before an upload, the Mega is designed in a way that allows it to be reset by software running on a connected computer.

When this line is asserted taken low , the reset line drops long enough to reset the chip. The Arduino Software IDE uses this capability to allow you to upload code by simply pressing the upload button in the Arduino environment. This means that the bootloader can have a shorter timeout, as the lowering of DTR can be well-coordinated with the start of the upload. This setup has other implications.

For the following half-second or so, the bootloader is running on the ATMega While it is programmed to ignore malformed data i. If a sketch running on the board receives one-time configuration or other data when it first starts, make sure that the software with which it communicates waits a second after opening the connection and before sending this data.

The Mega board contains a trace that can be cut to disable the auto-reset. The pads on either side of the trace can be soldered together to re-enable it. Revision 3 of the Arduino board and the current Genuino Mega have the following improved features:.

They operate at 5 volts. Each pin can provide or receive 20 mA as recommended operating condition and has an internal pull-up resistor disconnected by default of k ohm.

A maximum of 40mA is the value that must not be exceeded to avoid permanent damage to the microcontroller. External Interrupts: 2 interrupt 0 , 3 interrupt 1 , 18 interrupt 5 , 19 interrupt 4 , 20 interrupt 3 , and 21 interrupt 2.

These pins can be configured to trigger an interrupt on a low level, a rising or falling edge, or a change in level. PWM: 2 to 13 and 44 to LED: There is a built-in LED connected to digital pin The Mega has 16 analog inputs, each of which provide 10 bits of resolution i.

There are a couple of other pins on the board: AREF. Reference voltage for the analog inputs. Used with analogReference.
