Hands-on Design
Key Jail
For my Object Class, I designed and hand-crafted a "key jail". I connected my Arduino to a keypad and a servo motor that connected to a lock on the door. When the right input was given on the keypad, the servo motor would run and unlock the door (it would also lock back up!). This project shows my first real hands-on experience, combining code in Arduino, woodworking, problem solving, and design.
The perfect solution for all of your key troubles!
Losing your keys is no longer an issue, you won't have to carry them on a night out, having someone house sit is easy, and your friends can come and go as they please.
Wires
I connected a keypad to LEDs at the top of the jail and a servo motor that moved the lock inside. The red LED signals that the code was wrong and you should try again. The green LED illuminates when the code is correct and the servo moves the latch away so that the door can be opened. Both LEDs turn on when you hit the (#) or (*) and the servo moves to lock the jail again.
Enclosure
I built the jail frame from scratch using plywood, metal hinges, a sawtooth hanger, and wooden rods. I sanded each piece of wood using grits 80, 100, 120, and 220 sandpaper, then stained them using "Smoke Grey" Varathane classic wood stain.
Final Pictures
I am extremely proud of this project! Everything I have learned from this class was cumulated into this final project, working with Arduino to make a physical, real-life product that incorporated code and hands-on building skills. I was even able to dust off my wood crafting skills from high school to make the rustic jail!
