This document describes an electronic voting machine project created by three students using an AT89C51 microcontroller. The project uses KEIL software to create a hex file that is burned onto the microcontroller using a PHYTON CHIPPROG programmer. The hardware includes an LCD, microcontroller, crystal, resistors, capacitor, potentiometer, buttons, and a breadboard. Voters can select from four parties by pressing labeled buttons and results are displayed by pressing a stop button. Potential improvements include adding reject and confirmation buttons, fingerprint authentication, and connecting it to GSM for mobile voting.

Write code using embedded c.
Create hex file of code using keil software.
Burn hex file in microcontroller using prog+ kit.
Design circuit on breadboard as shown in circuit view.
Do Interfacing of LCD with microcontroller.
Supply +5v DC from USB port or any other sources.
Follow instruction as dispaly on LCD.
To start voting press start(init) button.
For voting press button P1: BJP, P2: CONGRESS, P3: AAP(AAM
AADMY PARTY),
10)
P4:OTHER PARTY.
To see the result(who win) press stop button.

8. Problem Faced During Project
8
Power supply
(no simple cell of +5v DC available in
market)
Sol: take USB port power supply


C-family microcontroller
(probability of project run using AT89c51microcontroller is
<25%)

9. FUTURE IMPLEMENTATION
9

Add Of Reject Button
(vote for no candidate if no one is suitable)

Add Buzzer
(for confirmation of vote)

Replace Voting Button With Fingerprint
(so that no one can revote)

GSM Module Electronic Voting Machine
(vote using mobile phone)

Marketing
(market price of this project=10 times that I pay for this project)
