Voltmeter

thingiverse

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) ##Team(authors) *Syimyk Taichabarov *Ermek Bakytov *Kubanychbek Mamanov Link for Youtube (https://www.youtube.com/watch?v=lcr29EAhzao) ##Parts list 1 - ARDUINO Uno R3 1 - LCD 16*2 2 - Resistor 10 kOM 1 - Resistor 100 kOM 1 - Potentiometer 10kOM Some Plastic Some wires 12 - screws 12 - nut 2 - mini tweezers(preferably)
