In this chapter, you learned how to use three common types of motors to create complex movement with your Raspberry Pi – a servo motor for creating an angular moment, a DC motor with an H-Bridge driver to create direction movement and speed control, and a stepper motor for precision movement. If you have grasped the general concepts of each of these types of motors, then you deserve a pat on the back! This is an achievement. While motors are simple in principle and their movement is something we take for granted daily in everyday appliances and toys, as you have discovered, there is a lot going on behind the scenes to make that movement occur.
What you have learned in this chapter, together with the example circuits and code, provides you with a foundation that you can use to start building your own applications where movement and motion are required. A simple and fun project could be to create a program to control a robotic car or robotic arm – you'll find...
