HH optical controller?

[Ronyd]

Hi Rob,

thinking about going optical for the HiHat. What resistance range is the module looking for the HiHat?

I'm assuming i need to know this in order to determine the resistor values (R1, R2) for the LED and PhotoTransistor.

I don't want to damage the module.

As long as the pedal input pins don't go above 3.3v, all is good.

thankx Rob
