Polling machine

Hey everyone, are you in a situation where all your friends are fighting on the decision we are making. The easiest option is to ask every body their opinions but this advance age. So we need a polling machine like the one use in elections. So let’s make it using arduino.

Connections:

1) One pin of push buttons to 8, 9, 10, 7of arduino

2) Another pin to GND of arduino

3) LCD RS pin to digital pin 12

4) LCDEnable pin to digital pin 11

5) LCD D4pin to digital pin 5

6) LCD D5pin to digital pin 4

7) LCD D6pin to digital pin 3

8) LCD D7pin to digital pin 2

9) LCD R/Wpin to ground

10) LCD VSSpin to ground

11) LCD VCCpin to 5V

12) 10Kresistor:

13) ends to+5V and ground

14) wiper toLCD VO pin (pin 3)

Are you interested in making your ownarduino project and rely on my sources.

If you rely on my sources then you might have your ownideas that neither I have not uploaded or nor others. So you might leave thehopes on completing that project. But there is no need for youas I will helpyou out personally. Yes you heard it right. I will complete your project. Allyou need is just to press this link.

LiquidCrystalLibrary - Hello World

Demonstrates the usea 16x2 LCD display. The LiquidCrystal

library works withall LCD displays that are compatible with the

Hitachi HD447BJP0driver. There are many of them out there, and you

can usually tell themby the 16-pin interface.

This sketch prints"Hello World!" to the LCD

and shows the time.

The circuit:

* LCD RS pin todigital pin 12

* LCD Enable pin todigital pin 11

* LCD D4 pin todigital pin 5

* LCD D5 pin todigital pin 4

* LCD D6 pin todigital pin 3

* LCD D7 pin todigital pin 2

* LCD R/W pin toground

* LCD VSS pin toground

* LCD VCC pin to 5V

* 10K resistor:

* ends to +5V andground

* wiper to LCD VO pin(pin 3)

How to use: if you want to vote BJP press push button connected to 8

If you want to vote congress press push button connected to 9

If you want to vote trs press push button connected to 10

If you want to vote tdp press push button connected to 7

If you want to change the the contestant you have to change variables

To check votes press all buttons together

Customization:

1) Write all contestant names in a paper and place it side to the assigned pushbutton

2) Add lcd at top
