Explorer Hat Pro, Output.three, on all the time


#1

I have a Raspberry Pi 3, Explorerhat Pro, and one led light on the breadboard.
I can control all the outputs except for output three. Output three is on all the time.

I have disconnected all the power, restarted the raspberry pi.
Re-seated the GPIO pins to the raspberry pi.
Typed eh.output.off() python.

Nothing seems to disconnect output three from the ground.

Do you have anything else running on the Pi which might be using pin BCM 13? It’s a PWM pin, so it could be something related to servos, or just some code running in the background that’s asserting that pin.

It finally stopped not sure why.
Thanks for looking in to it.
