ARDUINO keypad door lock system is used our home security,

It is very easy to do, with less of expensive watch each and every step carefully.

SO LETS START

Step 1: NEEDED MATERIALS:

1.ARDUINO UNO(NANO,MEGA)

2.SERVO MOTOR

3.CARD BOARD

4.JUMPERS

5.CONNECTING CABLE

6.LED(green,red)

Step 2: CONNECTING:

1.connect the servo motor to pin 11 on arduino

2.connect rows and column of the keypad to the pin 2,3,4,5,6,7,8,9 on arduino

3.connect servo GND to arduino GND

4.connect servo VCC to arduino VCC

5.connect LED(green) pin to 12.

6.connect LED(red) pin to 13

1.make room with card board.

2.place the open for the door.
