Build Your Own Arduino-Powered Sound-Sensing LED Wall Art

Anyone can hang a poster from the wall. If you’re willing to put a little more effort into your home decorations, this Arduino-powered LED wall art reacts to music playing in the room with different colour and effect patterns. You’ll need some space to build it, but it will look amazing.

This DIY project comes to us from Stathack, who you may remember from his baby bottle Wi-Fi antenna build a little while ago. This one’s definitely more complicated, and he runs down all of the parts you’ll need over at his website. In short, you’ll need a heavy-duty picture hanger, some MDF, lots of paint, sub flooring for the back of the piece, an Arduino Uno, a sound impact sensor (so the art can “hear” what’s playing in the room), LED strips, and the wiring and accessories to put it all together.

His carved the MDF and wood into the shape of a giant Darth Vader mask that lives right above the couch, but you could just as easily draw out and make your piece whatever you choose. Just keep in mind that it will be backlit by the LED strips when it’s finished, so you’ll want something that looks pretty cool with lights flashing around it. Hit the link below to check out the full project build, step-by-step, including the code you’ll need to get the Arduino working with the components he used.
