This project is a pin code based door lock system built with an Arduino Uno board. The device allows users to enter a 4-digit code (or more) the password can be a combination of numbers and letters to enhance the security and to avoid brute-force attacks.
- Arduino board - Uno is a good choice
- 4*4 Keypad module
- Breadboard
- M-M Jumper wires
- 9V battery (or any 7v -12v power supply)
- Upload the code.ino file to your Arduino Uno board using the Arduino IDE.
- Connect the keypad module and the LCD to the Arduino board according to the hardware connection map. 3- Power the Arduino board with a 9V battery. 4- Enter the pre-set 4-digit code on the keypad to unlock the door.
