A Simple Voltmeter





Introduction: A Simple Voltmeter

About: I'm engineer and like to design electronic and programming things with Arduino hardware.

This project was developed using OLED 128X64 LED Display 12C interface in conjunction with an Arduino Uno for measuring voltage. For uploading the code, go to the following website: http://pastebin.com/wBz3RVgr

Step 1: Bill of Materials

1 Arduino Uno R3

1 12C OLED 128X64 Display

1 Header of 40-pin

1 5cm X 7cm PCB

2 Wire jumpers for Arduino

1 12 in Heat Shrink tube (any color)

Step 2: Schematic

Follow step by step the diagram of your project so that you can complete it successfully. All of instructions are in this schematic and the indications are very clear so that you can undertand it and so you can do a great project because with this project, you could be measuring until 50V without problem.

Step 3: Complete Step by Step

Following your schematic, complete step by step correctly before uploading the code.

Step 4: Uploading the Code

Now, it's time of uploading your code so that you can enjoy this interesting project. Then, remember to visit the following website: http://pastebin.com/wBz3RVgr

Very nice tutorial and a very useful gadget.

If you dont mind i made a slight modification to use it with a Nokia 5110 lcd.

Thank you very much for sharing!

can you give the link of code in .ino extension

Nice work! Thanks for sharing. I'll have to file this away so I can build it one day.
