The Arduino Mega ADK (Rev3) is a microcontroller board based on the ATmega2560. It is designed to work with Android devices via its USB host interface, making it an ideal choice for developers looking to create Android-compatible hardware accessories. The board provides a vast array of I/O pins and increased memory capacity, which makes it suitable for larger and more complex projects that require additional computational power and connectivity options.
Pin Number | Function | Description |
---|---|---|
1-54 | Digital I/O | Digital input/output pins, PWM on 15 pins |
A0-A15 | Analog Input | Analog input pins |
GND | Ground | Ground pins |
5V | Power | Regulated power supply for the board |
3.3V | Power | 3.3V power supply derived from the onboard regulator |
VIN | Voltage Input | Unregulated input voltage to the board |
RESET | Reset | Resets the microcontroller |

What is the maximum voltage that can be applied to the I/O pins?
How do I reset the board?
If you are connecting the Arduino Mega ADK to an Arduino UNO or using it in a setup that involves Arduino-compatible code, here is an example of a simple sketch that blinks an LED connected to pin 13:
// The setup function runs once when you press reset or power the board
void setup() {
// Initialize digital pin 13 as an output.
pinMode(13, OUTPUT);
}
// The loop function runs over and over again forever
void loop() {
digitalWrite(13, HIGH); // Turn the LED on (HIGH is the voltage level)
delay(1000); // Wait for a second
digitalWrite(13, LOW); // Turn the LED off by making the voltage LOW
delay(1000); // Wait for a second
}
Remember to include comments in your code to explain the functionality, and keep the line length of comments within 80 characters for better readability.
