This project is going to introduce and explain how we can monitor circuit voltages. It is also going to introduce another basic tool commonly used in electric circuits. This tool is called a voltage divider. We won’t be using any new components in this project, but in case you’re new to the series I recommend you look into both this Arduino Uno Ultimate Starter Kit or go back and get the list of individual parts at the first Arduino Project to get caught up.
