a simple circuit of a voltmeter

or for more detail explanation you can refer to my blog



Step 1: Materials Required

1.arduino Uno or any arduino board


3.four 47 Ohm Resistors

4.Two 220 Ohm Resistors

5.Two 150 Ohm Resistors

6.some jumper wires for connection

for the circuit diagram,checkout pictures

and i have also uploaded arduino code for your convenience.
