security code lock system


Now a day’s security must be required for our home as well as for offices and also in industries at where we want to prohibit the entry of the peoples which are un-authorized.
To solve that purpose we introduce a micro controlled based digital code lock an access control system that allow only authorized persons to access a restricted area. That person has a lock excess password.
So to make security code lock system i used Atmega16 micro controller to process all the process.
and added LCD to make more user friendly device.
If any authorized person enters predetermined number via the keypad the relay operates for a limited time (it is about 6 seconds).So relay can be used to operate solenoid. Solenoid is an electronic lock, which can be used to open/close the door.When the code has been enters incorrect five times in a row keypad will be locked for few minutes, and it will be switched on the alarm.


 complete hardware with LCD and Keypad with out put of relay. and all thing are working on 12v DC
after giving power supply of 12v it will start and give this kind of display on LCD
  if password is correct then relay will open for some time. and if you want to reset password then we can reset it by pressing the reset password key and it can asses after only one password is correctly enterd
original display will come automatically

  1. Hi, here's some question from my side!!
    was this designed for home automation? If yes then tell me the expected price of this device?
    DO we have to enter the password everytime to make it work, or is there some other function to bypass the procedure?
