This project demonstrates how to create a simple voltmeter using an Arduino. The voltmeter measures the voltage of a given input and displays the value on the serial monitor.

One is digital voltmeter which shows the measurements on a digital screen and the other is an analog voltmeter that uses a needle to point on the scale to show us the exact reading. Digital Voltmeter ...
