Beginners • Re: GPIO pins false positives due to digital noise on Buttons

What is the source of the noise ? Perhaps easier to remove problems on the 'sender side' first.
Are there motors, valves, relay contacts which produce spikes. Flourescent lights are a common source of trouble. Are there HF sender module around ?

Use software filter to suppress short spikes "moving average filter".
I have a 5v and another 12v phone like power supplies near, a relay that lights a small single led and another led strip bar, cables from a pc monitor, I cannot remove any of these tho.

I'm using code from this post viewtopic.php?p=906425#p906425 to catch false presses
