Voltmeter using arduino amd LCD display.

Arduino can do a lot of things. This tutorial is about making Arduino voltmeter. Yes, it is possible and more testing equipment can be created using Arduino. First, shall we learn how to make a Volt Meter?

How it is worked?

The theory behind the voltmeter is the same method used for Voltage divider with resistors. As you aware, Anolog pins can read 0 to 1024 and the pin voltage is 5. Based on that we are going to start the coding.

Voltage divider theory is as follows;”
