Firmware types:
Doubling switch function: this version uses a toggle switch. When the switch is set, the tapped time will be halved. Tapping 100ms will result in 50ms.
Blinking LED function: this version uses a LED which blinks in sync with delayed signal. It works both when tapping than with setting the delay through the analog potentiometer.
ATTINY25 is flashed with a continously running application which senses each time you push a switch and set digital pot's resistance accordingly. Delay time can be se both with physical potentiometer than tapping footswitch.
