The Arduino Mega 2560 Rev3 is a Microcontroller Board based on the ATmega2560 chip. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. The board contains everything needed to support the microcontroller; the user needs only a compatible computer and software. Features include multiple communication protocols (such as I²C, SPI, and UART) and a large number of digital and analog pins. It can be used for a wide range of applications, such as controlling robots, home automation, and interactive media installations.
