Pardon me for the most stupid question of this month but I was looking into the code of my weather station, made by a much better programmer than me so I started to doubt my insight...
The Arduino Uno and Nano have only 2 interrupt pins, but in the code below, an interrupt is connected to another digital pin?! To me this is not possible but what happens if this is in the code? It cannot work, true??
The INT0 is used for the anemometer and INT1 is used for the RFM95 LORA module (DIO0)
RAIN_GAUGE_PIN = pin 6 in this case...
pinMode(RAIN_GAUGE_PIN, INPUT_PULLUP); // Config Pin as Input and turn on the internal Pull Up Resistor
attachPinChangeInterrupt(RAIN_GAUGE_PIN, rainGaugeClick, FALLING);
