Expression pedal

This is basic expression pedal. I created this to be used as midi controller via arduino. The pedal has turning angle of 45 degrees, which drives potentiometer for 270 degrees. This is version 0.2 and probably I ( or someone else ) will do more refining/adjustements on the design.

Potentiometer:
Body dimensions Ø17 x 9.5mm
Shaft diameter 6mm
Shaft length 13.5mm
Product code - R16110N-B10K
