Arduino Based Voltmeter | How To Make Voltmeter Using Arduino | Working Of Voltmeter
This is amazing project not only for college student but also for school students, in this video I am going to show you how to make a digital voltmeter using Arduino, and show the readings on LCD display.

For making the digital voltmeter using Arduino we have used an Arduino pro mini, analog input pin A0 of Arduino is used as input on Arduino, but we can use any other pin. Arduino have 10 bit of Analog to digital converter and our Arduino have five volt logic, so Arduino convert the voltage in 0 to 1023, and after calibration we can show this value on LCD display
In this project we also used a voltage divider circuit, which divides the input voltage and convert it into accepatable voltage for Arduino.
Components :
1. Arduino Pro Mini
2. Battery 9 Volt
3. Voltage Regulator 7805
4. 16x2 LCD
5. Voltage Divider Circuit
