Arduino Door Lock Servo

Arduino breadboard keypad 4 4 in this example cables one red led one green led two 100 ohm resistors servo only if we enter the right code on the keypad we want the green led to light up and turn the servo to a certain position lock open.

Arduino door lock servo.

The servo turns back to the position it was in after some seconds. A pin based lock using keypad and servo. The servo arm will be connected to the slider lock and will move to 0 degrees to lock the door and 60 degrees to unlock it using commands it gets from out bluetooth device. A latch can be attached to the servo e g.

The ground wire is typically black or brown and should be connected to a ground pin on the arduino board. Upon scanning the right tag and entering right pass it will open door and send confirmation message otherwise it will send alert message. The power wire is typically red and should be connected to the 5v pin on the arduino board. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.

Servo motors have three wires. To unlock and lock a door. Now we will connect the 16 2 lcd to the arduino. Just thought of making a password based door lock system in which you can enter the password via the keypad.

Arduino door lock with password. In this project i mede an door lock or box lock that opens when you enter your password and press. Connect all seven pins of the keypad to analog pins d1 d7 of arduino. To connect the servo motor with the arduino use digital pin d9 of arduino to output the pwm pin of the servo motor.

This is a simple arduino project. In this project we will do an automatic door lock system using a 4 4 keypad and servo motor controlled by arduino.
