Introducing Arduino MEGA 2560

In this section, we will briefly go through the Arduino MEGA 2560 board. We will understand how it is different from the Arduino UNO, and also see why we chose this board over the Arduino UNO.

The microcontroller

As mentioned before, Arduino MEGA 2560 is like a big brother of Arduino UNO. It is almost twice as long and way more powerful; Arduino MEGA 2560 is the successor of Arduino MEGA. Unlike Arduino UNO, MEGA 2560 has 54 digital input and output pins, as shown in the following image:
