Arduino Voltmeter

About Me:

I am a 16 year old electronics enthusiast who really enjoys designing electronic circuits and projects. I have been building circuits for about 3 years, and I have been designing PCBs for about half a year. I use Fritzing, Ki Cad, and Eagle.

About this project:

This PCB is the first revision of a voltmeter. This voltmeter will be able to test any battery up to 9 volts.

The voltage enters a voltage divider and then is read by an analgue pin of an Arduino Nano. The Nano then does a mathematical equation and displays the battery that is being tested on an OLED screen.
