![]() Typically used to add a reset button to shields which block the one on the board. Bring this line LOW to reset the microcontroller. There are a couple of other pins on the board:ĪREF. By default they measure from ground to 5 volts, though is it possible to change the upper end of their range using the AREF pin and analogReference() function. The Mega2560 has 16 analog inputs, each of which provide 10 bits of resolution (i.e. Note that these pins are not in the same location as the TWI pins on the Duemilanove or Diecimila. Arduino Mega 2560 Pin: 2 Arduino Mega 2560 Interrupt: INT0 Atmega2560 Pin: 6 Atmega2560 Interrupt: INT4. Support TWI communication using the Wire library. Get started with Arduino Mega projects using this comprehensive schematic diagram. When the pin is HIGH value, the LED is on, when the pin is LOW, it’s off. Find the Arduino Mega 2560 R3 schematic and learn about its pinout configuration, power supply requirements, and other technical specifications. There is a built-in LED connected to digital pin 13. The SPI pins are also broken out on the ICSP header, which is physically compatible with the Uno, Duemilanove and Diecimila. These pins support SPI communication using the SPI library. Provide 8-bit PWM output with the analogWrite() function. See the attachInterrupt() function for details. It has a crystal oscillator-16 MHz, ampere power jack, an ICSP header, a USB-B port, and a DEFAULT button. On the diagram, you can locate the ICs, such as the Atmega2560 microcontroller, the FTDI USB chip, voltage. It has the power, ground, clock signal, and all the ports labeled in order to help users find the correct signal or connection they need. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. Arduino Mega Pinout(Detailed Board Layout) Arduino Mega 2560 has 54 digital input/output pins, where 16 needle are analogous enter, 14 are PWM pins, and 6 are hardware serial ports (UARTs). The Arduino Mega 2560 circuit diagram is designed to be easily understandable and intuitive. Pins 0 and 1 are also connected to the corresponding pins of the ATmega16U2 USB-to-TTL Serial chip.Įxternal Interrupts: 2 (interrupt 0), 3 (interrupt 1), 18 (interrupt 5), 19 (interrupt 4), 20 (interrupt 3), and 21 (interrupt 2). The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. Used to receive (RX) and transmit (TX) TTL serial data. In addition, some pins have specialized functions: In this post, we’ll go over the capabilities of the Arduino. The versatility of the pinout provides many different options such as driving motors, LEDs, reading sensors and more. The Arduino Uno pinout consists of 14 digital pins, 6 analog inputs, a power jack, USB connection and ICSP header. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. Arduino Uno is based on the ATmega328 by Atmel. Each of the 54 digital pins on the Arduino 2560 Mega can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions.
