Hi guys, I encountered a problem on Arduino Uno R4 Wifi. I used the 2 interrupt pins which is the digital pin 2 and 3, and also it is connected to arduino cloud. On pin 3 a coin acceptor is connected while on pin 2 a water flow sensor is connected. The pin 3 works because the arduino reads the pulse but in pin 2 it doesnt read the pulses sent by the sensor. Did someone also experience case?
The problem could be in your sketch but you did not post it or it could be in your circuit but you did not post a schematic
Are you sure that the flow sensor is sending a pulse ?
