Controlling Alternating Current Devices with Arduino: Using Relays in Your Projects

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.

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.
