Design of smart electronic voting machine using Arduino

smart electronic voting machine

Objective of the project

Design of smart electronic voting machine using Arduino. The main goal of this project is to develop an electronic voting machine that will aid in the elimination of fraud in manual voting systems and previous electronic voting versions.

The system comes with a n number of switches, where n represents the number of political parties. The voter will be able to select their chosen candidate from a panel of buttons at this point. The final vote is then shown on an LCD to ensure voter satisfaction. Finally, the result can be calculated automatically by pressing the result button.

Components:

  • Arduino UNO
  • LCD display
  • Potentiometer
  • Push button
  • Connecting wires
  • Breadboard

Description:

Arduino UNO:

It is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller.

We used four push button for four distinct candidates in the election, all of whom are using Arduino. We can expand the number of candidates if necessary. Each time a voter presses one of the four buttons, the voting value is increased by one. The result button can be pushed after the entire voting process to display the outcome.

Circuit Diagram:

Assemble the circuit as depicted in the diagram. Connect the 5 push buttons to Arduino’s digital pins 7,6,5,4,3. Connect pins 4, 6, 11, 12, 13, 14 of the LCD to digital pins 13, 12, 11, 10, 9, 8 of the Arduino in the same way.

Working:

In this case, Arduino serves as the system’s heart and brain. The Arduino controls the entire voting process, including reading the button, incrementing the vote value, generating a result, and sending the vote and result to the LCD display.

Here, we’ve added five buttons: one for team A, one for team B, one for team C, one for team D, and one for calculating or displaying results.

Conclusion:

So we used a new technology of Arduino to create a machine for voting. This advanced technology is making more opportunities of evolution in electrical fields.
