Hi everyone it's Drew here. I'm very new to microcontrollers and just need to know here to start. At the moment I have a variable floating voltage input which I will regulate from 0 to 5 volts dc depending on circuit configuration. This voltage is on a single wire sent from a dc amplifier. I'm want…

Reading a floating dc voltage

There must be a common ground connection to define 0 volts potential.
