Hi,

I just realized that pin13 LED on my UNO is not responding. The sketch, I was running, was a simple sensortest, connected to A0 and blinking P13 if the sensor switches.

It looks like it is only the LED, because toggeling p13 shows 5V on voltmeter.

But how can it be , that only the LED is broken? And why? Can I change it?

It is possible to use an external LED, but I like this feature so much :)

thank you for helping

Did you remember to set the pin to OUTPUT?
