Very new to arduino programming and having difficulties creating a sketch that works for me.
I have an adruino uno in which I have placed two analogue inputs with varying voltages from 0-5 volts.
Using the analogRead code I have been able to read these voltages using the serial monitor.
If possible I would like to take both of my analogue inputs and subtract one from the other at certain intervals, I would then like to take this difference in voltage and display it.
Was hoping someone could help me out or tell if at all this operation is possible
