I am new to this so many apologies if I may have made a silly mistake here. However I was trying to drive an LED from the GPIO pins of the Pi ( I have a model 3 B+). I did the usual import RPi.GPIO and set the pin type to BOARD. When I go to activate pin 33 or pin 35 for example using GPIO.out and GPIO.high the LED does not light up and using a multimeter I can see that there is no voltage present at the pin 33. When I look at ‘readall’ in terminal to see what the state of the pins are, I can see that they are all in the input state initially. However when I set them to GPIO.output, they do seem to go to output state however only then revert back to input state once I set the pins to GPIO.high. Pins 3 and 5 seem to be the only pins that behave themselves and work without issue according to the code, none of the others produce any voltage when they are set to GPIO.output and GPIO.high. Except the dedicated 5V pins and the dedicated 3v3 pins. Any ideas on this issue would be greatly appreciated as I have tried every option and nothing seems to work (my Pi is also only a week old so don’t think it could be broken).
Thanks for the help peeps.
