An Arduino-powered automatic guitar footswitch
If remembering to hit your foot pedal at the right time during shows is a challenge, this device will take care of it for you.
As creator Franco Molina points out, there’s a lot to worry about when playing guitar in front of an audience. Actually playing is one thing, but you have to pay attention to the crowd, move around on stage, make sure you don’t have any wardrobe malfunctions, and… hit a footswitch to change between clean and distorted channels when appropriate.
Molina’s device may not be able to help you with everything on that list, but by listing to a specially encoded ‘click track’ from a computer or MP3 player, it can automatically switch amplifier modes when appropriate. It does this by using an Arduino Uno along with an amp to listen to the track, then switch a relay to simulate a footswitch.
