You're now a master of observing information from the world around you. But how can you control that world? Blinking LEDs and automatically adjusting nightlights are a good start, but you can do so much more. Using assorted types of motors and actuators, and with the help of transistors, you can use your Arduino to generate physical action in the real world. By pairing motors with your Arduino, you can drive robots, build mechanical arms, add an additional degree of freedom to distance sensors, and much more.
In this chapter, you will learn how to control inductive loads like direct current (DC) motors, how to use transistors to switch ...
