Digitise an older engine - ESP32
#27
I am now trying to get the RPM sensor to work for me, it seems you made your own board, but I already had a Optocoupler board based on the EL817 that I used for my ST1 connection (https://amzn.to/3Kkoy2q).  Running the code below:

Code:
(new DigitalInputCounter(RPM_PIN, INPUT_PULLUP, RAISING, 500))

it seems the voltage to at the pin never drops, I think I should try:

Code:
(new DigitalInputCounter(RPM_PIN, INPUT_PULLDOWN, FALLING, 500))

any thoughts?
