Open And Closed A Servo Door Lock Via Bluetooth

In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matrix.

Open and closed a servo door lock via bluetooth.

After tying in the servo with the latch the servo must be put in a suitable position preferably in the middle of the latch so that the open close motion can be achieved properly. Compile the code and upload the coding to the arduino. To unlock the door. Mert arduino 129 724 views.

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. From here we could add a sensor like a knock sensor so we can unlock our door with a special knock or even a voice recognition system. Turn on bluetooth in the mobile enter into app if on the door lock will be open. Now press on the send button and aha.

First of all i tied attach the servo motor to the door lock as shown in the image. Multi servo motor control via bluetooth using android app arduino and app inventor duration. This is a simple arduino project. Go to the analogwrite message group tap on the button displaying 8 and adjust the analog value with the help of the scroller to 180.

Actually i set two command one is open and another is close and password may contain any digit later or symbol or combination of them as you like. 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. From here we could add a sensor like a knock sensor so we can unlock our door with a special knock or even a voice recognition system. If you select 90 then the servo will move 90 degrees instead of 180 degrees.

Note that 180 is the degrees you want to move the servo shaft. The code for bluetooth control smart door lock is very simple.
