The access control system is the system that is used to control theentrance channel, which is developed on the basis of the traditionaldoor lock. The traditional mechanical door lock is only a simplemechanical device, and no matter how reasonable the structural designis, how strong the material is, people can always open it throughvarious means. The key to the entrance and exit (like an officebuilding, a hotel room) is cumbersome. If the key is missed or replaced,the lock is to be replaced with the key. In order to solve theseproblems, the electronic magnetic card lock and the electronic codedlock are present, which has raised the management level of the accesschannel to a certain extent, and then the channel management enters intothe electronic age.

I love Cyclops and I made the coolest door lock ever. From past one month I was planning to make an RFID door lock system. But I wanted something cool. I am huge fan of Xmen. I love Wolverine and Cyclops. So created an RFID based door lock system, where if you swipe the right card, his known "eyes" will turn green and servo will open giving a beeping sound through a buzzer. If you swipe the wrong card, his eyes will turn red. So here is how I made.


The box is made out of beech plywood 5mm and consists of 2 drawers locked by solenoid mechanisms and a main door locked by a servomotor. It features 4 electronics puzzles to be solved :


This instructable was created in fulfillment of the project requirement of the Makecourse at the University of South Florida (www.makecourse.com). The goal of this project is to develop the prototype for an RFID door lock. An RFID consists of a scanner and a card. When the card is placed on the scanner an action usually takes place. In this case it will be turning a motor to unlock the door.


The control system for the project is shown in the block diagram. It starts with the RFID scanner. Once the RFID scanner finds a RFID card that matches up to it, it sends a signal to the Arduino. The Arduino then sends power to the stepper motor from the battery, if the switch is on, to tell it to move to simulate the door unlocking and locking. The breadboard setup is shown along with the schematic and Fritzing model. The stepper motor is wired through the driver to the Arduino. The RFID scanner is wired to the Arduino as well. The power is given by a 9V battery with a switch. The RFID card is programmed into the code so it can be specialized to increase security. If there is no RFID card the system does nothing, but keep the door locked. The Fritzing model can be referred to if there is any problems in setup.








The project uses an Arduino Uno as the basis for the coding. Connected to the Arduino is the RFID scanner and Stepper motor. The attached code, functions, and needed libraries are used to turn the stepper motor when the RFID card is placed on the scanner. The stepper motor is currently set to unlock the door, wait 3 seconds, and unlock the door. The Stepper motor library is used to call on movements for the stepper motor specifically. The RFID library (MFRC522 in this case) is used to initialize and run the scanner with the card. The functions file is used to store blocks on the card to personalize it and add a security measure.




The code is divided into 3 sections. The first section defines the needed libraries and variables. This is where all the pins are defined, libraries are found, and variables are done. The next section sets up the system. It initializes the SPI, the RFID scanner, and stepper motor to ensure all are ready to perform their own actions for the code. The last sections is the loop where the actions are sent to the system. This is where the loop is defined the make the stepper motor move if a card is identified to simulate the door unlocking and locking. The code is commented and described to show exactly what each line does for the system.



From this the code can be altered some to better fit a certain need or project depending on what you are using this for. For the motor's speed, the gear ratio in the code can be altered to get a different gear ratio from it. In addition to this, the current code has a 3 second time delay in it to open the door,get through the door, and close the door. This was mainly used for presentation purposes. This can be changed to a more appropriate time to get best performance.


At this point, the black box should have all of the components in it and wired up correctly with a working code. Test it out to ensure the rack and pinion system is working correctly with the stepper motor and RFID systems as shown in the video. Once this is done it is time for the finishing touches and mounting it on the door. Inside the box there is four short places to drill which is where the mounting screws will go for the door. Drill these holes out along with the correct place on the door. For the door itself, the box should go where the deadbolt was. Align the old dead bolt location with the new one and the box should be mounted as such. If the handle is not mounted on the door, do this now as shown in the door handle manual. Once that is done, the project is complete and you have yourself an RFID door lock.


The final product is shown in the pictures and video. One picture shows the final from the outside while the other shows what it looked like from the inside. The video shows the full working model. The project is able to turn on from the switch, read the RFID card using the scanner, send a signal to the stepper motor, and have the stepper motor turn to unlock the door. A short time later (3 seconds for this case), the stepper motor moves again to move the rack and pinion system and lock the door. The door can then be switched off to save battery life.


Recently I wanted to create an Arduino-based low-power Internet of Things (IoT) device for makers, with built-in sensors that could be used to deliver sensor data from any location to the cloud, and potentially control connected devices such as thermostats, lights, door locks, and other home automation products. Along the way, I learned that creating a new IoT device, from idea to prototype to final product, is not as simple as I thought it would be, and there was no "ready-to-go" development device to start with. However, by figuring out how to do it, I created a new product called Siguino, an open source IoT circuit board, that I hope will make it easier and faster for other people to create their own IoT products.
