Foot Pedal - double

thingiverse

Double foot pedal. Why do you need one? In my case my daughter play violin and needed an automatic page turner for her sheet-music. Software like MobileSheetsFree can do that for you. You only need a double footswitch. I took the design of Atiesh , https://www.thingiverse.com/thing:3152310 doubled it, made some modifications to it and I had a doubvle switch. By the way, it should be wireless. No problem for MobileSheetsFree. So I added a container to the pedals to store my BlueTooth transmitter. I used an ESP32 as BlueToothTransmitter. Then I needed a battery which can be charged with a simple mobile charger. In the end I covered the container with a transparant lid so you can see all the electronic and the lights.
