/v_show/id_XNjIxNzQyNzY4.html I live in a small apartment in Shenzhen with my wife and baby, 5 months old. Sometimes, I need to go out, for example, to go downstairs to buy candy or diapers for my baby. But always I forget to carry my keys, so I need to knock at the door or call my wife to open the door for me, and, always wake up my baby and begins to cry. At this time, I am so guilty. So i decide to think of a way to fundamentally solve the problem. A fingerprint lock would be help for me, and there are plenty of these kinds of locks on the market, as the picture above. But it is not only expensive, and, it is also very troublesome to install. I hope to find a cheap way and do need not change my locks. After learning Arduino for 2 weeks, I decided to DIY a fingerprint lock, with Arduino. Step 1: Solution and Module PreparingShow All Items First, I observed the door of my house, as the picture above. As you can see, as long as the red part of the figure pulled in the direction of the arrow, the door can be unlocked, and of cause, when not pulled, the red part go back to it’s original location to lock the door.
So I think, a servo would be OK to accomplish this function. And, i need a fingerprint sensor, too, when i or my wife press the fingerprint sensor, which can determine whether a person is certified, it outputs instructions to the Arduino, to control servo to open the door. I use the following modules: 1. Crowduino，this is an Arduino compatible microcontroller boards, i use it because it is cheap enough, and has some upgrading on the design, such as the reset button on the side. 2. FingerPrint Sensor 3. A servo with enough torque. 4. Glue，or anything that can be used to fix these modules 5. 5V USB power supply or 9V DC jack power supply 6. Some jumper wires would be help. « PreviousNext »View All Steps Download Smart locks are now widely available, and allow users to open & close a door by the press of a button on their smartphone. Some locks are even connected to the cloud, and allows the user to open/close it remotely, and share the access to the door with other people.
In this project, we are going to build our own DIY version of such a smart lock, that can be controlled from anywhere in the world, as we'll connect it to Adafruit IO. However, we'll add a twist in the project: we will actually also allow the user to control the door lock by using their fingerprint. And as the fingerprint sensor will also be connected to the Adafruit IO platform, it will be really easy to make both devices talk to each other. Show All ItemsAs a person without a car, I don't need to carry keys around everywhere I go. Because of this, I've been locked out of my own house several times. It's a pain to wait for someone with a key, so I thought I would do something about it.This project is my way of solving this problem, while getting the chance to interface with an awesomefingerprint scanner (aka: FPS). Also, this module isn't restricted to just garage doors, for you can create different kinds of simple motorized locks to suit your needs.Step 1: MaterialsShow All ItemsElectronics:PartSupplier (pictures are clickable!)

The build requires some soldering, wiring, uploading code to an Arduino, and circuit board construction, but the end result sure is impressive. His case for the whole setup is 3D printed and offers the plans for download.
Of course, if you don't have a 3D printer, you could probably find another creative way to house it all. He also points out that this setup isn't restricted to garage doors either, and you can create different motorized locks to be used with it.It's a complicated project, sure, but it's way cooler than a hide-a-key!
