Based on the reverse engineering from Whitelamp and the PWM implementation from @santoxyz
This is an emulator for the VFS5 Vox footswitch for their own amps running on a Arduino nano.
- 5 Buttons (4 channels + 1 Bank selection)
- 4 LEDs to indicate channel (1-4 solid, 5 - 8 slow blinking)
- Powered directly by the amp.
- Printable case

LEDs go on Pins: 7,8,9,10:
Pin ----- 330Ohm ----- LED ---- GND -
Buttons go on Pin 0,3,4,6 and use Pullups:
Pin ---- BTN ---- GND
- Simple Case: if you design something more elaborate drop me a note.
- Supports 5 Cherry Style keyboard switches (press-fit)
- Supports 4 5mm LEds (press-fit)
- Supports 5x7 PCB (press-fit)
- PCB holder a bit to small => the PCB needs to be trimmed by 1mm
- Screw-holes to small to fit a nut => the case fits okayish without screws, otherwise use longer screws so the nut is on the top.
