Electronics voting machine is a very interesting and very wonderful project to
explain the wotking of microcontroller and eerom. In this project one LCD is
also connected. One keyboard with feq switches are connected it to feed the
data in the eerom.
Here we use ic 89c51 microcontroller as a main processor. Pin no 40 is
connected to the positive supply. Pin no 20 is connected to the ground pin. Pin
no 18 and pin no 19 is connected to the crystal pin. Here we use crystal 3.58
Mhz. In this microcontroller there is total four portís. Port0, Port1, Port2,
Port3. In this project we assign only four candidates. So therefore four
switches are connected to the microcontroller to enter the volt for each
candidate.Four other switches are connected to the microcontroller to check the
One switch for the total vote.
Two switches for the reset the processor.
Here we use two by 16 line lcd. For the display.
