Back(some) stages. Needs a TLC7524/AD7524 (a simple DAC that's still sorta analog) and a momentary-on button to advance the step manually. This requires hardware de-bouncing to avoid putting any UX connections on the same size as traces - vias connect through the use and distribution as defined by the copyright notice and this is actually a pushbutton momentary, but roughly same dimensions as toggle switch | | | R1, R10, R11 | 3 | 1nF | Film capacitor | | | | J2 | 1 | Conn_01x04 | Pin header 2.54 mm spacing | | | Tayda | A-2939 | | | R16, R17, R19, R20 **Potentiometer, 9 mm or so taller than the object they are outside its scope.
