I'm an absolute beginner to making robots.
I'm looking to make a robot using the Rover 5 (4 motor with 4 encoders), and an arduino as the brains.
Based on what I've read, to drive all 4 motors as well as read all the encoders, the arduino UNO doesn't have enough pins, so an Arduino MEGA or Red Back Spider is needed. as well as the Dagu 4 Channel 5-12V, 2A Brushed DC Motor Controller, or something similar which provides enough power to the motors, and communicates with the arduino (or spider).
First question is, is the above correct?
