I bought some of these foot switches a while ago and never used them, until I noticed this board. Does this simply require omitting the on board LED? Or does it need to be shorted or something?
It’s been a minute since I used one but I had adjusted the resistor to taste. And jumpered the LED pads on the PCB I believe, Is this the technically correct way? Not on that. I don’t remember how I came to that conclusion. if I remember correctly Red required a lower value resistor to achieve my desired brightness.
