Hi there, put the thing together, but the LED doesn't work. Changed resistor for LED, put a new LED in, same result. I have no idea. Someone has the same experience? Thx U4U
Do you have a picture of your circuit by chance? There are many things that can cause LED faults.
Thx 4 reply, got it, as I had written and posted an idea comes to my mind. There's an issue with the ground pad for the LED. Now it works. Thx again, U4U
