In this Instructable I am going to show you how to build a Voltmeter with a big Nokia 5110 LCD display using Arduino.

Building a Voltmeter is a great learning experience. When you finish building this project you will have a better understanding of how Voltmeters work, you will refresh your knowledge of Ohms law, and you are going to see in action how powerful the Arduino platform can be. With this project as a base and the experience gained, you will be able to easily build more complex projects in the future.

You can use this project to measure DC voltage from varius electronic circuits or monitor the battery state of your Arduino projects easily. Also, with the knowledge gained you can easily build your own voltage sensor to create your custom Voltmeter that fit your needs.

Without any further delay, let’s get started!

The parts needed in order to build this project are these:

1. An Arduino Uno http://bit.ly/Cheap_Uno
   
2. A Voltage Sensor http://bit.ly/VoltageSensor
3. A Nokia 5110 LCD display http://bit.ly/NOKIA5110
4. A Small Breadboard http://bit.ly/Small_Breadboard
5. Some wires http://bit.ly/Wires3InOne

The cost of the project is very low. It is about 10$.
