Hello !

I will show you how to make a voltmeter * with Arduino UNO, an OLED screen, 2 resistors and 9 jumpers for less than 5 minutes. With it, you will be able to measure the voltage from 0 to 30V (if you exceed it you risk damaging your arduino!). Let's start!

* “A voltmeter is an instrument used to measure the electrical potential difference between two points in an electrical circuit” – Wikipedia, the free encyclopedia
