| Feb 21, 2023 at 13:28 | comment | added | m5c | I guess I see the main issue now though… I put the ground on the wrong side of the switches. The GPIOs are not connected to ground in default button state. I guess that’s why you meant by « subject to interference » ? @Milliways See: raspberrypi.stackexchange.com/a/69475/152237 | |
| Feb 21, 2023 at 12:53 | comment | added | m5c | Thanks, updated the image for a schematic. I also listed the code for the handlers, which was further down in the linked python script. @Milliways the reason for using a pin as power is that the device also contains a stepper motor and a display and I was running out of pins. Could you elaborate why it is not recommended to use a GPIO as power supply? | |

| Feb 21, 2023 at 12:10 | comment | added | joan | It's not clear why you are powering from a GPIO. Why not use a 3V3 pin? Also it's not clear if the buttons are defaulted high or low. A proper schematic would clarify the situation. | |
| Feb 21, 2023 at 12:10 | comment | added | Milliways | It is far from clear what you have done. Draw a proper circuit not pictures of buttons. As far as I can see the buttons are using internal pull down which is subject to interference and for some bizarre reason using another pin for power. But no code to actually DO anything. | |
