To be able to control AC loads with Arduino, a relay is always required for the switching so the high voltage can be separated from the low control voltage of the Arduino.
These relays come in many shapes and sizes, and each relay holds a different load rating so it is important to understand how they work and how we can safely use them in our projects.
In this video, I'm going through the basics of what a relay is, how it works, and how it can be controlled with Arduino so you can then incorporate them into your projects.
Check the project Instructable for a written version of this video. You can also find the Arduino code used in the video there.
