kit2 2:9bdba6204bb4 1 /* Digital Lock System
kit2 2:9bdba6204bb4 2 Components Used:
kit2 2:9bdba6204bb4 3 NGX Baseboord
kit2 2:9bdba6204bb4 4 MPR121 Capacitive touch panel as keypad( p26, p9, p10)// IRQ, SDA, SCL
kit2 2:9bdba6204bb4 5 LCD for display(p24, p25, p27, p28, p29, p30) // rs, e, d4-d7
kit2 2:9bdba6204bb4 6 Motor for opening/closing the lock(p11, p12) // for input in H Bridge
kit2 2:9bdba6204bb4 7 Baseboard SD Card for storing Forest.wav
kit2 2:9bdba6204bb4 8 Baseboard audio jack 3.5 mm
4180_1 0:e09703934ff4 9
kit2 2:9bdba6204bb4 10 By using touch panel as input we enter the desired password to open the lock.
kit2 2:9bdba6204bb4 11 Initially we store a password in array ORG[] which can be compared with the password(length= 7)entered by the user.
kit2 2:9bdba6204bb4 12
kit2 2:9bdba6204bb4 13 If the entered password is correct then motor opens the door.
kit2 2:9bdba6204bb4 14 In case of wrong password the user is asked to re-enter the password. 3 trials are given after which door is permanently
kit2 2:9bdba6204bb4 15 locked.
kit2 2:9bdba6204bb4 16 Option to change the password is also provided.
kit2 2:9bdba6204bb4 17 The process is guided by display of instruction on the LCD.
kit2 2:9bdba6204bb4 18
kit2 2:9bdba6204bb4 19
kit2 2:9bdba6204bb4 20 Under Progress:
kit2 2:9bdba6204bb4 21 An attempt is being made to guide the user by playing relavent audio files along with the instructions on LCD.
kit2 2:9bdba6204bb4 22 The "forest.wav" file is the one that we are attempting to play along with LCD instructions.
kit2 2:9bdba6204bb4 23 the bit rate of the wave file is 176kbps.
