Door lock with Arduino (Let's Print Youtube Channel)

FULL BUILDING AND TUTORIAL VIDEO: https://youtu.be/AdwotLcc6GU Klick HERE to see my other projects. 3D printing and Arduino is just a perfect match, this is the first video on this channel using Arduino. Where I got the idea to make a door lock? - Well the RFID module is just soo cool and I wanted to use that and where is better to use this then door lock? I have seen on Youtube also where people had build door lock with RFID module using servo motor, but never seen with stepper motor, soo I give it a try. I am planning to make a project where I use Arduino a lot more.
