This is a project from [Mirel] who built the system around a Arduino Mega 2560 and antipodal Vivaldi antennas, a type of directional antenna. Everything is mounted into a small cart that can be ...

For this project I am using the Arduino Mega 2560. Absolute Number of Steps Matter First, we should consider the number of steps needed for a full rotation of the motor shaft. In this prototype I used ...

Apparently, so does [salmec] who developed the Mowerino around an Arduino Mega 2560 board. As you might expect, the robot uses sharp blades so, you probably want to be careful.

PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...
