It has two telephones, which have the intercom facility, and can be connected to the telephone line. All functions are controlled by the 8-bit AT89C2051 microcontroller that has a 2 kilobyte program memory (ROM).
The DTMF (double frequency multiple frequency) signals are decoded by the DTMF IC 8870 decoder and its output will be in decimal of the pulsed key. The switching function is performed using 12V relays.
Electronic voting has been a hotly contested issue since the presidential election in the United States in 2000. Many security flaws were found. The standards for implementing electronic voting systems proved to be too weak and many more. India is the largest democracy in the world. It is perceived to be charismatic, as it accommodates cultural, regional, economic, and social disparities and is still able to stand on its own. The fundamental right to vote or simply to vote in elections is the basis of Indian democracy. In India all previous elections are state elections or central elections, an elector uses to cast his vote to his favourite candidate by placing the seal against his name and then doubling the ballot according to a prescribed method before putting it In the ballot box . This is a long, time-consuming and error-prone process. This situation continued until the electoral scene was completely changed by the electronic voting machine. No more ballot, urns, stamping, etc. All this condensed into a simple box called the voting machine's electronic voting machine. EVM is able to save considerable stationery printing and transporting large volumes of election material. It is easy to transport, store and maintain. It completely excludes the possibility of invalid votes. Their use results in a reduction in voting time, resulting in fewer problems in electoral preparations, law and order, candidates' expenses, etc. And easy and accurate counting without any mischief in the counting center. It is also ecological. There are two forms of voting: distance and presence.
