PROGRAMMABLE COMBINATION LOCK CIRCUIT PIC16F84

Prepared by: F. San – 1 relay control circuit pic-16f84 is based on the keypad’s LED indicators and buzzer alert source. Bass. Hex code and simulation files have isis proteus. Thanks to the people who contributed to prepare.

4 × 3 matrix form lock password is entered via a keypad connected. As soon as the circuit programmable lock password is 1234. Activate the relay output that is keyed to unlock and then # 1234 is printed. If the password error relay is energized. To change the current password, for example, in 1961: 1234 * 1961 # 1961 # to be monitored as a key sequence. Changing the password fails, the old password will remain valid.
