![]() ![]() PWM: Among 54 I/O pins 15 of them have PWM capability which can be used to generate PWM signals for controlling the brightness of LEDs or the speed of motors.Interrupts: The processor has 6 interrupt pins that can be used to trigger events in response to external inputs.Watchdog timer: The board has a watchdog timer that can be used to reset the board in case of a software failure.These timers can be used for a variety of purposes, such as controlling the speed of motors or generating PWM signals for controlling the brightness of LEDs to name a few. Timers: The ATmega2560 contains several timers, including a 16-bit timer/counter with PWM and a 8-bit timer/counter with PWM.Analog-to-digital converter (ADC): It has 16 10-bit analog input pins that can be used to read analog signals, such as those from sensors.Here are some of the peripherals provided by the processor of the Arduino Mega ADK: The board is equipped with a variety of peripherals to support various types of projects. The power supply should also be able to provide enough current to power the board and any connected peripherals.Īrduino Mega ADK Rev3 Pinout and Peripherals It is really important to note that when using an external power supply, the voltage should not exceed the maximum voltage range of the board to avoid damaging the microcontroller. ![]() The voltage range for this method is 4.5-5.5V DC.
