Following discussion, Mr String has realised that teachers and students can freely access the IT Lab as there is no door security. He would like a digital security lock to be added to the door linked to the alarm system.
To open the door a 4-digit code will need to be typed into the keypad. If the code matches the stored code, the lock will display ‘Door unlocked’ if the code does not match the lock will display ‘Incorrect code’ and an alarm will sound.
