Published on Dec 05, 2020
In this modern world people are forced to use electronic devices in their daily life. Now day's electronic voting machines are used for election. Here we introduced a cellular voting machine based on micro controller.
In this system there are two units, a master unit and a voting unit.
The voting unit is placed anywhere and the master unit is placed in a control room. The voting unit contains a DTMF coyer, which generates a DTMF tone and is transmitted to the master unit through the FM transmitter.
The master contains a FM receiver, DTMF decoder, Micro controller and Display units. The tone from the voting unit is received by the receiver and is decoded and specific functions are carried out by micro controller and then it is displayed.
