Control an LED display with your electric guitar!

Control an LED display with your electric guitar!

Have you ever wanted to have a light show that reacts to what you play through you’re favorite electric instrument? Georgia Tech grad student Wil Roberts has, and so he created a guitar-controlled LED display–an impressive project that combines both his Maker and musical chops.

To accomplish this, Roberts used an Arduino Uno along with an Adafruit 16×32 RGB LED matrix panel that responds to the guitar’s signal. The bottom rows are always blue, while the top ones progress from green to red the louder he shreds. The top rows remain red depending on the length of the note being played.

Want one of your own? Roberts has made all of the display’s circuitry and code available on Instructables. In the meantime, be sure to see it in action below!
