Beginning Arduino

Summary

Chapter 5 showed you how to use motors in your projects. It also introduced you to the important concepts concerning transistors and diodes; you will use both of these components a lot in your projects, especially if you are controlling devices that require larger voltages or currents than the Arduino can supply.

You now also know how to construct a H-Bridge and how to use it to change the direction of a motor. You have also used the popular L293D Motor Driver IC; you will work with this chip later on in the book when you look at a different kind of motor. The skills required to drive a motor are vital if you are going to build a robot or a radio controlled vehicle of any kind using an Arduino.
