More info


The Arduino MEGA 2560 is based on ATmega2560 MCU.

He has 54 digital input/kinds (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTS, a 16 MHz quartz oscillator, a USB connection, a power jack, an ICSP connector, and a reset button.

It contains everything needed to fly the microcontroller, simply connect it to a computer with a USB cable to use it simply.

Version Rev3 (R3):

1.0 Pinout: 2 pine (SDA and SSL) are added next to the AREF pin and 2 pine (IOREF and a reserve) are added next to the RESET. These pins will be added on the next shields.

Improved reset circuit.

ATMEGA 16U2 replaces the ATMEGA 8U2.

What is that the Arduino?

Arduino is an open-source electronics prototyping platform that consists of components and easy to use software.

Who is Arduino?

The Arduino kit is intended for artists, designers, enthusiasts and all who are interested in creating interactive objects.

How to use the Arduino?

The Arduino can detect are environment with the addition of sensors that you connect on its pine trees of entries.

Just then retrieve that information and process them by programming the Arduino using the Arduino development software (free). You can then drive outputs which will act on other elements like the LEDS, displays, motors, and many others.
