Arduino - Home Made DIY VOLTMETER

Introduction: Arduino - Home Made DIY VOLTMETER

About: Hello world! I make simple & Advanced projects for people who want to learn programming and electronics. Most of my Instructables are about arduino and the wide range of sensors you can use with it. I make…

Hello world! Today i made a simple VOLTMETER With arduino, Follow the next step for the Schematic. Code and Parts List. Its pretty easy to build and very handy if you don't have one.. like me. I never used a multimeter in non of my projects lol. I should buy one! I needed to repair a laptop charger for a friend but i could not test it because all my laptops had different plugs, so i made this. Have fun with it!

Step 1: Schematic, Code and Parts List.

Just wire it up like the schematic, and it should work after uploading. You need to solder the resistors to a prototype board, or you can use a breadboard of course. It's pretty easy to build.

Parts list.

  1. Arduino uno, i used the RobotDyn Uno. (has 8 analog pins)
  2. LCD 1602
  3. Breadboard or a PCB ProtoType Board.
  4. 10k Potentiometer.
  5. 5x 10k Resistor
  6. 2x 2.2k Resistor
  7. Jumper wire set MM/FF/FM

Good luck!
