Chapter 8. Bot Control
At this point in the build, after we hook up the motors and connect the motor controller to the Pi, we could remotely log into the rover and control it from a laptop. If you were to add a battery for the Pi and at least one for the motors, the rover would be technically ready to test outside. But don’t do that yet. It might behoove us to connect everything first, debug the inevitable wire crossings and incorrect hookups, and then take it outside.
Connecting the Motors and Motor Controller
Setting the sensor connections and the robotic arm aside for a moment, let’s go through the process of hooking up the motors so we can test the movement. You’ll need to set aside six GPIO pins for the motor controller—three for each motor. ...
