Hey
Im doing a digital code lock as my third year project, the specs are as follows must use a 4x4 keypad, password/code must use letters and numbers, when u enter the correct code a solenoid opens the door, if u enter the wrong code 3 times No access appears on the LCD and buzzer is sounded. Also all numbers are displayed as * on the LCD, and finally i must be able to change the code at anytime and make it whatever length i want.
My coide is complete up to the point where i have to be able to change the code at anytime. If anyone could help me with this final part it would be very much appreciated.
