  2. Arduino Board
  3. LDC 16 x 2
  4. Relay
  5. Transistor
  6. Resistors
  7. LED

Description

Circuit schematic like in figure 1 above is Arduino Digital Code Lock with LCD Display and User Defined Password. his project is a much improved version of the same digital code lock which comes with a user defined password and LCD display. The user will be prompted to set a password at installation. This password inputted at installation will continue to serve the lock until it is changed. The user can change the current password with a single key press. The program will check for current password and allows the user to change password only if the the current password is input correctly.
