Controlling high power AC load using relays
Control of high-power devices, such as 120V power outlets, is an objective of home automation. While a Raspberry Pi Zero cannot power devices on its own, it does can control relays that are designed to control power sources.
Note
Working with AC power, such as 120V house power (also known as line voltage), is extremely dangerous and potentially lethal. Do not ever attempt to work with live circuits, and always work with experienced electricians when designing systems that control power. Mishandling high power can be deadly!
Getting ready
For this recipe, you will need a protective relay. The one included in the Elegoo Kit works perfectly for this recipe, but any relay that takes a 5V DC switching input should ...
