Communication Protocol: IC Max232

To convert the TTL/CMOS logic levels to RS232 logic levels during serial communication of microcontrollers with PC

PC works on RS232 standards (-25 V to + 25V).

The controller operates at TTL logic level (0-5V)

• The intermediate link is provided through MAX232. • It is a dual driver/receiver that includes a capacitive voltage generator to supply RS232 voltage levels from a single 5V supply.

Binary logic levels:

Future Scope

Applications:It can be used in taking group decisions where voting is confidential.It can be used in companies, industries, Schools, Colleges or anyPrivate or Government Sectors. It can be used for different purposes not only for voting system.

Advantages:Tampering is not possible.Good security can be achieved by using this technology.

Process for voting would be very easy.

Disadvantages:• If Micro controller is damaged, then it’ll be difficult to re install, program and solder the part.• There must be scrutiny of the persons because RFID card is transferable and there can be a chance for a person to come with other person’s card.• Extreme care must be taken to protect the entire circuit/PCB from getting damaged.

Future scope:• A timer could be included, which could automatically end the voting after specified duration of time.• Biometric verification of voters, so that automatically it can be insured that one person is voting only once.• It can be made more interactive by adding sound effect (speech) to it.• EEPROM can be used to store the data permanently.• If we make more than one EVM, each to be used at all different locations and the final result is the addition of result of all, we could think of connecting them to communicate with each other and final result can be shown on one of the LCD.• Touch can be implemented in place of switches.
