Relays are key to using your Arduino to directly control devices that work on alternating current. This trick enables you to use a far greater variety of components in your projects, and in this case, it’s one of my favorites: electroluminescent wires. In this video, you’ll use this eye catching and fun device to showcase the powerful relay technique.
What You Will Learn
Discover the different types of relays available and how they work
Use relays with Arduino
Switch on and off a strip of electroluminescent wire (a device not normally compatible with Arduino)
Who This Video Is For
Beginning-intermediate Arduino users – people who have built a few projects and are looking for ways to incorporate a greater variety of components into them.
In this video, you’ll use this eye catching and fun device to showcase the powerful relay technique. Relays are key to using your Arduino to directly control devices that work on alternating current. This trick enables you to use a far greater variety of components in your projects.

Welcome to this tutorial where I’ll show you how you can control alternating current devices using an Arduino and a relay.
First, a little bit about me. I’m Hannah, a writer and maker with a background in physics. But for a few years now, I’ve been making whimsical inventions with microcontrollers.
You can find these on my YouTube channel, HannahMakes, or in publications like New Scientist Magazine where I’ve written about things like my tea bag dunking robots and the shoes I made that call you an Uber when you click your heels together three times.
