Voltmeter

Main goal of this project is to show to u volt of some electrical thing

There is will two tweezers, by them u will touch some electrical thing that u want, after they LCD will show how many volt have thing that u toucing. There is one thing u must to know it will show only volt from 0 to 30. In another way on screen will just nothing.How u can see in image under arduino was 2 resistor (R1,R2) After when will print all of thing u can just connect tweezers to wires from this 2 resistor. Hole in cap of cover is 2.5 mm (diameter). Connections between lcd display and arduino board:

R1 100kohm Resistor
R2 10kohm Resistor
-LCD D5 pin to digital pin 5

LCD D6 pin to digital pin 6
LCD D7 pin to digital pin 7
LCD RS pin to digital pin 2
LCD Enable pin to digital pin 3
LCD D4 pin to digital pin 4
LCD R/W pin to ground
LCD VSS pin to ground
LCD VCC pin to 5V
10K resistor:
ends to +5V and ground
wiper to LCD VO pin (pin 3)
