In this chapter, we learned about the first component that adds movement to our bots: the motor. We learned about the types of motors, and how to interface one with a microcontroller. Then, we wrote code to test our motor with the Pi hat and the REPL, and we built a small randomized cat toy using our knowledge of the Johnny-Five Motor object. Finally, we built a project that allowed us to explore hands-on the abilities of the Motors object and write code to drive a two-wheeled robot.
