This Converse Shoe Has A Built In Wah Pedal
This upgrade to the Converse Chuck Taylor’s allow you to create guitar wah effects by simply moving your foot up and down. With input/output jacks on the heel, it uses a digital sensor to manipulate the amount of effect that’s applied.
As you can see, the implementation of this project is pretty transparent. Using a flex sensor located within the shoe, the sensor sends data to the Arduino device, proportionate to based how much the user elevates their heel.
