If you like solving puzzles out in the real world, you’ve probably been to an escape room before, or are at least familiar with its concept of getting (voluntarily) locked inside a place and searching for clues that will eventually lead to a key or door lock combination that gets you out again. And while there are plenty of analog options available to implement this, the chances are you will come across mor ...

Here is a project for locking and unlocking with a tilt sensor by tilting it in a defined sequence. It uses an accelerometer module to detect the tilt motion. If the sequence matches with the predefined motion sequence, the lock opens. You can build this lock for a briefcase, ballot box, portable cashbox or even as a door-lock using suitable mechanical arrangement. Circuit and working Fig. 1 shows circuit d ...

About Burglars Recently the Spiegel published an article about burglars in Germany: Burglars prefer the dark months. In december the insurances report 3 times more housebreakings than in july. The police reports that it is very difficult to find the delinquents. Mostly there are no witnesses and no traces. Only in 2,6% of the housebreakings the culprit can be condemned. Burglars do not only break into house ...

You have seen RFID Door Lock Mechanism in some Hotels and other places, where you don’t need a key to unlock the room. You are given a card and you just need to put it in front of a RFID Reader box, and the lock gets unlocked with a Beep and a Blink of LED. This RFID Door Lock can be made easily at your home and you can install it in any door. These Door lock is just electrically operating door lock which g ...

Security is a major concern in our day to day life, and digital locks have become an important part of these security systems. There are many types of security systems available to secure our place. Some examples are PIR based Security System, RFID based Security System, Digital Lock System, bio-matrix systems, Electronics Code lock. In this post, let us build a Secret Knock Detecting Door Lock using Arduin ...

This a door lock built as fun project.It is quite easy to build and a fun way to learn and improve your knowledge of arduino.I tried to add a 16*2 display but there werent enough GPIO pins on arduino Uno.If You are interested in adding a display you would need an arduino Mega. Items Needed Arduino UNO Jumper wires Servo(or anyother component to open a door lock like a linear actuauator) Keypad(I used a 4*3 ...

This is an electronic garage door opener designed around a SparkFun GT-511C1R fingerprint scanner. There is already a very good instructable by user nodcah that describes how to build almost this exact device, from which I took 99% of my inspiration. I'm posting this to easily share with my local makerspace, and for anyone who likes to see things done slightly differently. The door opener system consists of ...

Thanks to everyone who supported this project and voted for it in the Arduino Challenge! I was awarded second prize and hope to participate in more Arduino contests in the near future. This tutorial will explain a simple way to make a password protected bluetooth door lock using your Arduino, which can be unlocked by sending a four digit pin from your Android phone!  The hardware setup is quite simple,  and ...

Time for something different  - a single button combination lock. Allow me to explain… Updated 18/03/2013 Normally a combination lock would require the entry of a series of unique numbers in order to unlock something or start an action. For example: A more contemporary type of lock could be controlled electronically, for example by a keypad where the user enters a series of digits to cause something to ...

The Arduino RFID lock How does it work? The Arduino RFID lock is a lock that can be opened easily, but is secure. The lock works with a server database that can register card codes. On the door there is a RFID reader connected to the lock. If the RFID reader reads a registered card the door will open. One of the pictures gives a  schematic overview of the functionality of the Arduino RFID lock. In this inst ...
