In this chapter, we saw how to control devices from the Raspberry Pi Zero board, which is critical in any smart home that you want to automate. First we looked at how to control and dim an LED, which you can use to control LED-based lighting and LED strips in your home. We also looked at how to control the speed of a DC motor, which you can apply to control the motor of a garage door, for example. Finally, we saw how to control any appliances in your home, such as lamps, using a graphical interface running on your Pi.
You can, of course, already use what you learned in this chapter and adapt it to your own projects, for example, by applying everything you learned in this project to control several devices from the same interface running on your Pi.
In the following chapter, we are going to apply what we learned in this chapter by building a smart energy meter based on the Raspberry Pi Zero.
