Power LED Blocks Audio in Bent Book Strip
« on: January 04, 2020, 12:20:44 AM »

I'm bending a small book strip and I'm trying to add a power switch with an LED to show the unit is turned on. The power switch seems to be working fine, but when I test the LED in line, it cuts all audio from the unit. The LED does light up when the unit is powered on, though. I've tried placing it in several different points on the circuit and it does the same thing every time. Does anyone know why it would block audio like that? Is there a different way you're supposed to wire up a power LED that I'm not aware of? Any help would be greatly appreciated!

I'm not sure what you mean by inline, but wire a power LED across the positive and negative rails, and use a current limiting resistor.

I had my wiring wrong. That solved the problem, thank you. And thanks for the link, that'll come in handy.
