Door Knock Sound

We're going to go slowly and check as we go. What are the main components to do something like this? If you're lucky the legs will be the right length and you're ready to go!

Wrap some of the remaining wire around the strip so that it stays out of the way. In this section we make the all important part that connects the motor to the lock. Some transistors might have the pins in different order. We're going to upload our sketch before doing any of the electronics so we can test the electronics as we go.

This can be raised as high as if you have a very sensitive detector. The edge with the holes is the side that attaches to the motor. When you're done the pattern you just tapped should repeat on both lights.

When you do cut these, hot glue the suction cups in one end and stick the other ends in the right angle connectors on the ends of our legs. This is a good time to label the other end with a piece of tape. What we're making is a clamp that attaches to the D-shaft of our motor and fits easily over the lock latch so that it can turn the lock. You could just use a piece of tape or even glue or screw it straight to your door, but doing it this way keeps it portable.

If it doesn't hear a knock for this long it will assume it's done and check to see if the knock is any good. The higher torque the better. You can increase this if your secret hideout is protected by devious drummers with good memories. Open the sketch and compile it.

Measure and mark the center line from top to bottom. And the bluetooth camera is a great idea of added security. Lowering these means someone must have more precise timing, higher is more forgiving.

Enjoy and I hope you find a great place for this sound! The story behind the sound is super exciting if you are an urban explorer on the hunt for abandoned places around the world. First lets make sure our legs are the right length. If you think that was all?

Professional problem solver. What a waste of resource and work for nothing. Read through it carefully and be sure you understand it before you start!

This started out as a bit of a joke project, but turned out to be surprisingly accurate at judging knocks. And the transistor for that matter. Be sure the lock clamp is attached to your motor and the legs are in place.

Countersink the screws if possible. Feel free to build a completely different and more functional case. Follow whichever one you're the most comfortable with. Just follow the road on Google maps. Or any other way you can think of to get v to the Arduino.

If you're not sure if you have these skills, read through the entire Instructable and make sure you understand it before starting anything! If you never make mistakes you can skip this step.

Add an H-Bridge to the circuit so it can lock and unlock the door. If you get knock messages without tapping it may be too sensitive. Protect your secret hideout from intruders with a lock that will only open when it hears the secret knock.

The batteries might die, the suction cups might fail or you might forget your knock. You knock correctly and it still doesn't open. We shouldn't need them any more. We're almost there, all we have to do is cram all that wire and the circuits into the pipe.

You should really start to see it take shape. Might as well test again it since it's all hooked up.

Add a real-time clock and using different knocks for different days of the week. Of course, I recorded the sound of it and an older lady came up to us and gave us some fruits.

Now we have to put it into something more permanent that we can stick on our door. There are many ways to do this project, korean traditional music and you will have to make changes based on how your door and lock works.

Basic knowledge of microcontrollers I'll be using the Arduino. We're just testing for fit here.

Did you make this project? Do the first test from the inside.

Solder one lead from the switch to the resistor. Attach the battery in a similar way somewhere where it can power the Arduino. Having the door unlatch too makes it that much more mysterious. Rather than breaking something important. This distance is how much zig we're going to bend into each piece of metal.
