Pulse counter counts when input remains high

dansity commented 1 year ago

The problem

If I'm missing something please let me know, but I have this frustrating scenario: I want to build a wind speed meter (anemometer) which has a reed switch with a magnet. Sometimes the wind stops and the magnet is in a position when the input remains high and the pulse counter keeps counting pulses. For me it seems like it is checking the pin every cycle and if it is high it adds a count. However it should only count if the state of the pin changes from low to high. This is what I'm experiencing: L H H H H H - > 5 count registered however it should be only one when low goes high

Something similar happened to me and the problem was caused by a buck/boost DC converter that I used to feed a rail on the breadboard and it generated a lot of noise.
