This is mostly a copy-paste of the code I found on Google,
I want to make a project using 2 waterflow sensors in which inflow() which shows how many liters i have taken in and outflow() which shows how many liters flown out.
This is how far ive reached, Need help with the code please, I am not a advanced coder so descriptive code and support is HIGHLY appreciated. also please see the maincode(), in that section i am trying to achieve a loop, i mean if sensor1 is high it should display sensor1(inflow()) output ,and if sensor 2 is high it should display sensor2(outflow()) output.
Problems faced: the output doesn't work when i call both the inflow() and outflow() together, one function works,(i think it has something to do with the Interrupt Pins of the board?).
