It is a nice project and easy to implement. You are required to know about the LCD interfacing so that you can understand the concept behind voting machine easily. I have implemented this circuit on proteus and hardware both.
Hardware is also easy to implement. You just have to interface LCD and connect a momentry switch to a particular pin of microcontroller.
Working of voting machine: When we start the project it initializes to zero. as we press the switch, value is increased by one.
I have used a general purpose register of microcontroller and register is initializes to zero when it starts. It checks the status of switch regularly. when switch is pressed value of register is increased by one. As we know that LCD always display ASCII value. It is not able to display the hex or decimal value. To display the number as ASCII value, i have stored the ASCII value from 0 to 9 in program memory. So that we are able to pick the equivalent ASCII value according to the stored value.
