Electronic Voting Machine Using Seven Segment Multiplexing With 805 In this project i am going to tell you how we can make a prototype of electronic voting machine using 8051 microcontroller with 7 segment display. step 1: software used: as we are showing proteus simulation so for coding and simulation you required:. This is a prototype of electronic voting machine. here in this project we are using 4 seven segment display and in port 2 only we have connected all 4 segmen.

Electronic Voting Machine Using Seven Segment Multiplexing With 805 Seven segment display: in this project we are using four common anode displays. four push buttons: we are using four push buttons and, with a builtin pull up resistor in port 2, we are not using any resistors. to connect a pull up resistor, you can use port 0. usb to uart converter: this is a 9 pin d type male connecter for rs232 o p. Based on these inputs, the vote count for different candidates is increased by at89c51. sbit switch 1=p3^2; input pins for four candidates. to display the vote count, four seven segment displays are also connected to the microcontroller (refer seven segment interfacing with at89c51). the count value for each candidate is sent to the. The atmel at89c51 is an 8 bit microcontroller from the 8051 series. the atmel 89c51 contains 128 bytes of ram and 4kb of flash programmable and erasable read only memory (perom). it can be programmed and wiped a total of 1000 times. p1, p2, p3, and p0 are the four ports on the at89c51's 40 pins. The circuit uses at89c51 microcontroller and the code for the project has been written in c. this lcd based electronic voting machine is designed for four candidates. the input part consists of a set of six tactile switches. the switches and 16×2 lcd are interfaced to microcontroller at89c51 for various operations and displays.

Electronic Voting Machine Using Lcd And 8051 Microcontroller The atmel at89c51 is an 8 bit microcontroller from the 8051 series. the atmel 89c51 contains 128 bytes of ram and 4kb of flash programmable and erasable read only memory (perom). it can be programmed and wiped a total of 1000 times. p1, p2, p3, and p0 are the four ports on the at89c51's 40 pins.

The “electronic voting machine” basically consists of four main blocks. these blocks are keypad, microcontroller, lcd display and control switches. keypad: we have 8 keys on the keypad. thus it has one key specified for one candidate. this block is used in both voting and counting mode, in voting mode key of respective candidate is pressed. This voting system was constructed using an 8051 microcontroller and six push buttons. in this arrangement, polls 1 through 4 were allotted to a total of four contestants. to prevent pollers from voting multiple times, a poll control switch was introduced, which should be controlled by the poll supervisor.
