Working on the PPCB Minnow. The build features an on/off LED and a rate LED. My pre-drilled enclosure has a single center-drilled hole for the LED. Could I use a two-color LED with a common anode/cathode?…
When I've used bi-color LEDs, I switched between them.
I'm not sure how they will behave if both anodes are connected at the same time.
Not sure why you're saying that the rate led doesn't go to ground... according to schematic, it does:For this build I was thinking that the cathodes would be shared. Thing is, the bypass LED goes to ground, the rate LED doesn’t.
Edit: saying that out loud, I realize I’m a dummy. Both LED’s go to ground (obviously). I was thinking of it in terms of the rate LED shutting off when the pedal is bypassed. Which is no big deal. I’m gonna try the common cathode…

Oh... yes... Switch off, both color off... switch on, solid color and blinking "mixed" color for rate... that's what I understand.I meant the same ground. The bypass LED goes to ground through the switch. I was thinking that because the rate LeD would go out when the pedal was bypassed, it wouldn’t. But it would. It’ll just go off when the pedal does. That’s fine for me…
No. I cannot think of any way you could convert common-cathode to common-anode — if you were to physically try that you'd break the LED's casing and destroy the LED. Not worth the time and effort to even try that, I'd just get the LED needed.Is it possible to make a common cathode LED a common anode LED, or are they stuck just the way they are?
