Code urgently needed!!!!
Hi!
I need the code for my project of electronic voting machine with following specifications.
1) I am using IC AT89C52.
2) There are 4 seven seg displays, hence max no. of votes that it can store is 9999.
3) I am using 4x4 matrix keyboard. Therefore there are max 16 candiadtes. i want to use max 15 candidates. The last key will be used to enter into the password protected area.
4) the password protected area is used by machine operator to count the votes that each candiadate has got.
5) when voter enters the vote LED should glow to display that vote has been entered. Also LED should glow when the password is accepted.
6) Seven seg display is interfaced to port 0 through resistors of 220Ω each. of 89C52 and 6 LEDs to port 1 from P1.0 to P1.5.
7) The seven segment display i am using is in common anode mode. The transistors used are PNP transistors (BC557) for logic selection. the trasistors are connected to port 2 from P2.7 to P2.4.
Thanks and Regards!
