Using more then 2 interrups on arduino
-
I am in the process of building a sketch where I want to use 2 pulse meters.
The Arduino has only 2 IRQ hardware ports.
One is already being used bij the radio.....Any idea how I can solve this ?

@AWI Do you mean, remove the radio from pin 2 and use it for something else ?

Also, Google pinchangeint. It's a library that allows the Arduinos to use more pins as interrupts. Yes, you don't need to connect the radio to pin 2 and you can use it for something else.
Cheers

THx for the feedback. Now I can start to build my two pulse meters.
One for my electricity usages and one for my natural gas usages.Bert
