Download Arduino Mega 2560 Pins Background. With 54 digital i/o pins, 16 analog inputs and a larger space for your sketch it is the recommended board for 3d printers and robotics projects. It is designed for more complex projects because as for simple projects large amount of input output pins are useless and a board with less.

The mega 2560 is designed for more complex projects. Each of the 54 digital pins on the arduino 2560 mega can be used as an input or output, using pinmode(), digitalwrite(), and digitalread note that these pins are not in the same location as the twi pins on the duemilanove or diecimila. 1 arduino / yourduino mega 1280 and 2560 diagram and pinouts:

The arduino mega 2560 is a replacement of the old arduino mega, and so in general reference, it will be called without the '2560' extension.

The mega2560 has 16 analog inputs, each of which. Each of the 54 digital pins and 16 analog pins on the mega can be used as an input or output, using pinmode(), digitalwrite(), and digitalread() functions. I know basic electronics so far no, there is one pin per node, and a common ground pin which is the negative terminal. On your mega2560 are 5 ground pins (effectively.
