Arduino Voting machine

Picture of Arduino Voting machine
This instructable will teach you to build a simple Arduino based Voting machine using simple components such as push buttons and LCD. The highlighting feature of this system is that Serial Monitor in Arduino IDE is used to perform the polling operation no other external applications needed.
Key Features:
  • Every step of polling operation will be under control of the supervisor.
  • Password enabled security system.
  • Poll results can be obtained instantly.
  • Voter will be aware of the candidate he is voting for.

Step 1: PARTS REQUIRED

This simple project can be done with minimal components. The parts list are given below
  1. Arduino Uno - 1
  2. 16x2 LCD -1
  3. Push Buttons - As required
  4. Potentiometer 100k - 1
  5. Breadboard - 1
  6. Connecting Wires - As required.

Step 2: DESIGN

Picture of DESIGN
The design of the voting machine was given here. The Arduino reads the keypad input by the process of Polling. A 16x2 LCD was connected to the PORTD in 4 bit mode. This system will be operated by plugging the Arduino to the your PC and controlling using Serial monitor of Arduino IDE.

Step 3: PUT IT TOGETHER

Now connect the buttons to a breadboard as shown in the diagram. You can increase the number of buttons you use based on the number of candidates for the poll. Afix the LCD along with the potentiometer to the board and finish up all the connections as shown in the schematic design.

Step 4: ADD YOUR ARDUINO

Now connect your Arduino to buttons and LCD in the breadboard. You are now all set with the hardware.

Step 5: CODE AND WORKING OPERATION

You can read the detailed working operation and code in this websitehttp://www.gadgetronicx.com/arduino-based-voting-system/ . Upload the code to your arduino after obtaining it from that site.

Step 6: OPERATING WITH SERIAL MONITOR

Now you are ready to go and operate your voting machine. Connect your Arduino to the PC using the USB. Now open the Serial monitor to conduct the poll. Enter the password to get access to the system.
V - Allow Voter to caste their vote
D - Display the Vote tally.
Take a look at the snap shot of serial monitor to get understanding of its working.

Step 7: WORKING VIDEO

See the outcome of this system in this video which is uploaded to official channel ofGadgetronicx .

ABSTRACT

MULTI USER GSM BASED DIGITAL SCROLLING LED DISPLAY WITH PASSWORD AND VOICE ABSTRACT The project mainly focuses on transmission of textual data through air interface by the use of GSM through asynchronous serial communication. The data will be processed by the microcontroller it programmed by embedded c language by using KEIL C compiler. The data will be displayed on led display on LED only after entering unique pass key. Existing System: How a reliable and an authentic wireless communication could be easily developed between a mobile phone and microcontroller using GSM (Global System for Mobile Communication) MODEM (Modulator-Demodulator). This technical paper explains GSM based e-notice board which can be widely used for multitude of applications including educational sector, traffic control, banks, and public advertisements, stoke exchanges etc. Proposed System: In this project we not only send the data, but send the data with pass code also. Which enables us to preve...

A SHOULDER SURFING RESISTANT GRAPHICAL AUTHENTICATION SYSTEM

A SHOULDER SURFING RESISTANT GRAPHICAL AUTHENTICATION SYSTEM ABSTRACT Authentication based on passwords is used largely in applications for computer security and privacy. However, human actions such as choosing bad passwords and inputting passwords in an insecure way are regarded as”the weakest link” in the authentication chain. Rather than arbitrary alphanumeric strings, users tend to choose passwords either short or meaningful for easy memorization. With web applications and mobile apps piling up, people can access these applications anytime and anywhere with various devices. This evolution brings great convenience but also increases the probability of exposing passwords to shoulder surfing attacks. Attackers can observe directly or use external recording devices to collect users’ credentials. To overcome this problem, we proposed a novel authentication system PassMatrix, based on graphical passwords to resist shoulder surfing attacks. With a one-time valid login indicator and ...
