LED and button problem
Hello everyone. I am using a nano v3 biscotte to make a lightsaber and I have a problem. I connected: speaker, LED and battery and do push-button function by touching the two cables. when everything is connected, it turns on but does not go out, and if I disconnect the LED turns on and off perfectly. I have reviewed the welds 20 times and I got a little crazy.
any ideas?
Thanks
Ok, just to make sure I understand, when you have LED, Battery, and Speaker attached and you touch the two wires, the LED comes and and you get the idle hum. You then touch the two wires together again and the LED and idle hum stay on.
Now, if you remove the LED, when you touch the two wires you hear the idle hum, and then when you touch them again the hum stops. Correct?
exactly
Pictures of your wiring would be helpful. It sounds like you may have something connected incorrectly.

No a picture of the actual wiring on the board and components, with closeups of the welds as well.Originally Posted by alucutu
I tried with three LEDs

It appears that you have two negative wires running to your LED? The blue negative from the LED pad on the board, and a black wire?

In the diagram why do you have a wire going from the FoC pad back to the Battery(-)? Did you do this on the actual board and wiring?
blue go to negative nb and black wire go to positive battery
