ELECTRONIC VOTING MACHINE USING 8051 MICROCONTROLLER PDF

We have made sincere attempts and taken every care to present this matter in precise and compact form. We are sure that the information content in this volume would certainly prove useful for better insight in this scope and dimension of the subject. The task of completing the project though being difficult but was made quite simple ,interesting and successful due to deep involvement and complete dedication of our group members. We also acknowledge with thanks Prof. Deshmukh, Head of the Department of Electronics and Telecommunication Engineering for the support and facilities in the labs. We thank our beloved Principal Dr.

This project brings you the design and programming of building a very simple, cost effective polling machines which can do great job for elections in schools, colleges or particular locality. The highlighting feature of this voting machine using microcontroller is that the results of the poll can be viewed instantly also can be monitored from time to time over the period of the poll. This voting machine was built around Microcontroller which uses 8 push buttons Poll 1 to Poll 8 which was assigned for a total of eight candidates in this design.

To avoid multiple votes by the pollers a poll control switch was added which should be controlled by the supervisor of the poll. A LCD was used to display which candidates they have voted. And at last Hyperterminal should be used with the microcontroller to see poll results using serial communication.

But at first Poll control switch must be pressed to make the Poll switches available for voting. So every time a vote is casted the control switch must be pressed in order to allow the next candidate to vote.

This avoids multiple votes from the pollers. The Poll control switch was monitored by means of external interrupts. A LCD was used to display the status of the voting machine i. Also it will display the candidate name once a vote is casted. The vote results can be obtained by using a hyperterminal in a computer connected with , this was done by using the concept of serial interrupts.

Any button press in the keyboard will create interrupt and the vote results will be send to the computer in order starting from candidate 1 to candidate 8. Votes can be now casted using the Poll switches Poll 1 to Poll 8. Now the Poll control switch must be pressed again in order to allow next one to cast their vote, this allows the Supervisors to control the votes. The results of the poll can be obtained in the computer screen with a single press of any key in the keyboard.

You can get the vote results whenever you needed.

Normal light bulbs produce light by heating a metal filament until its white hot. LEDs present many advantages over traditional light sources, including lower energy consumption, longer lifetime, improved robustness, smaller size and faster switching. LEDs Piezo Buzzer This buzzer is a piece type audio signaling device, which has a piece element and a oscillating circuit inside which oscillates the piezo brass base plate, which when given voltage difference produces the sound of a predefined frequency. Piezo Buzzer These high reliability piezo buzzers are applicable to general electronics equipment.
