Topic: analog Voltage Reader (Read 963 times) previous topic - next topic


I'm sure this is a really simple answer but I'm completely forgetting it as I haven't worked on my Arduino in a month. What would the code be if I wanted one of my analog inputs read a voltage coming in. Not from a sensor or anything, just a voltage. It's going to be the voltage from my power supply so my robot will alert me when it's running out of battery. Any help would be great!
Thanks! :)
