Team 16 - Final Controller FNAF Tablet

 For our controller, we built a tablet design controller to mimic the camera display for the game Five Nights at Freddy's. Our original concept included light switches for the lights and slide switches for the doors. Our final project has 11 photoresistors on the top of our controller, each of which individually opens one of the 11 cameras displayed in FNAF. There are two toggle light switches on each side of the “tablet”. There is also a digital button on the front of the “tablet” that allows the player to enable and disable the pop-up monitor, where the player can then switch between cameras. We wanted to have a controller that a clear and easy to understand game to controller connection. Each of the cameras is mapped within the controller to match the in-game display. The controller allows the player to experience FNAF like never before, without the use of a mouse, and with intuitive controls for the left and right side controls. The format of the controller allows for a strong visual-to-physical control scheme. Does the visuals of the tablet support the in-game controls?

Jonathan Tsigas - Designed and sketched the prototype, then designed the final controller in Tinkercad. While working on the prototype and final, Jonathan handled many of the physical tasks of shaping, cutting, and screwing in the hardware to fit inside. Jonathan also did much of the write-up and final assignment delivery. 

Mason Kuhn - Handled the wiring and programming for the prototype and final controller. Mason soldered and wired the breadboard for the prototype and the circuit board for the final. He also wrote and tested the code to work with the Circuit Playground.
