Here are some of mini-project challenged for our readers:

• In this chapter, we discussed interfacing inputs for the Raspberry Pi and controlling motors. Think about a project where we could drive a mobile robot that reads inputs from whisker switches and operate a mobile robot. Is it possible to build a wall following robot in combination with the limit switches and motors?
• We discussed controlling a DC motor in this chapter. How do we control a stepper motor using a Raspberry Pi?
• How can we interface a motion sensor to control the lights at home using a Raspberry Pi Zero?
