Introduction: Secret Knock Detecting Door Lock

Picture of Secret Knock Detecting Door Lock

This project was inspired from Grathio. I saw his video on Koreus and thought about doing the same thing for my final project in College. I added some functions to the program. It works very well.

Here is the Arduino Code and the LabVIEW program


Instructions, parts list, and/or a site with instructions for this project? I would like to see what this does and possibly built one myself.


Bill Thomas

For the instructions, follow the guide Steve made. It is the exact same way I did it. Therefore, I made a PCB for the circuit, changed couple of things in the arduino program to fit it with my needs and finally made a LabVIEW program that will take a photo of the person that fails the knock sequence. If you have any other questions, I have a report that I made for my teacher, maybe this could help you more. Just let me know

Great project! A question though, is the microphone located in the door or the door frame?
