Introduction: How to Make Simple DC Voltmeter Using Arduino UNO

About: We run YouTube channel and provide some video tutorials on electronics and programming and also videos on cool projects - how to make them, tech news and more. Subscribe to our channel. :)

It is very clear from the title what we are about to make. So without any delay, let's begin.

We have made a video tutorial about this project. If you want to know the simple theory behind the coding, then do watch the following video. If you like our work, then please like our video and do subscribe our channel.


Step 1: Gather the Componenets

Things we will need for this project:

  1. Arduino Uno
  2. Breadboard
  3. 16X2 LCD screen
  4. Jumpers
  5. 2 resistors of 1k and 100E
  6. 1k Potentiometer

Step 2: Make the Circuit

Follow the circuit diagram and make the following circuit. It's very easy.

Step 3: Upload the Code

Upload the following code into your Arduino.

Step 4: It's Done!

Let's wrap this up. Just plug in the battery or any voltage source to measure and you can see the voltage written on the LCD screen.

I hope you have enjoyed it. Leave a thumbs up in the video. SUBSCRIBE to our channel.
