Arduino Door Lock Servo

In this project i mede an door lock or box lock that opens when you enter your password and press.

Arduino door lock servo.

A pin based lock using keypad and servo. Just thought of making a password based door lock system in which you can enter the password via the keypad. Now connect the positive wire of buzzer to the pin d10 of arduino and negative wire to the ground. To unlock and lock a door.

Servo motors have three wires. The servo turns back to the position it was in after some seconds. Upon scanning the right tag and entering right pass it will open door and send confirmation message otherwise it will send alert message. Arduino door lock with password.

In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matrix. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit. This is a simple arduino project. Power ground and signal.

Now we will connect the 16 2 lcd to the arduino. A latch can be attached to the servo e g. The power wire is typically red and should be connected to the 5v pin on the arduino board. The ground wire is typically black or brown and should be connected to a ground pin on the arduino board.

In this project we will do an automatic door lock system using a 4 4 keypad and servo motor controlled by arduino. To connect the servo motor with the arduino use digital pin d9 of arduino to output the pwm pin of the servo motor.
