Wiring the system
We're using a standard 5v phone charger to power the system. The entire package consists of an Arduino, a servo, an RFID reader with two tags (two people), and lots of tape. It cost $40 total with all parts from Amazon. Here, my roommate is wiring up the power along the wall. It is important to note that no college-provided furniture was damaged in the process and that both the RA and administrators approved the project.
The Inner Package
We bought a random enclosure off Amazon and stuck an Arduino in it. We're planning to 3D print a new enclosure sometime soon. The enclosure is directly above the servo, and the servo is taped to the inner deadbolt lock turner thingy.
Door Close Sensor
The system also knows if the door is closed so it can automatically lock itself. We haven't programmed this functionality however, as we just rigged this up in the middle of the night.
A Better Shot of the Servo
The servo head is four pronged, which worked out nicely!
Taping up the RFID Tag Reader on the Outside of the Door
The reader needed to be on the outside of the door because the door itself was solid oak. We made sure to tape it up tightly though.
The Entire System
A shot of the entire system taped up and completed, right before turning it on. Not shown is connecting the arduino and running the program that we had written previously. We'll upload the code to GitHub if anybody wants it, and OP promises to deliver.
Soldering Random Stuff
It works! Each flash either retracts or extends the deadbolt. Bye bye keys~
This is my first time posting something like this, so please do tell me if I can improve anywhere!
To be added: internal buttons to lock/unlock the door via buttons instead of physically rotating the servo, bluetooth module and android/iOS apps for proximity unlocking.
