With a simple knowledge of Arduino and Voltage Divider Circuit, we can turn the Arduino into Digital Voltmeter and can measure the input voltage using Arduino and a 16x2 LCD display.
The circuit diagram which is used to build this arduino based voltmeter is given below. You can connect the arduino and other components as per the diagram.
Once all the components are connected you can write the code for Arduino. Here is the link given from where you can download the arduino code for voltmeter.
