Car Track Puzzle is a puzzle designed for an escape room where you input a code you get from a cypher on a poster, releasing a car down a track that flips flags that spell a name. The keypad works using an Arduino and 4 buttons labeled 6, 7, 8, and 5. The code for the Arduino uses an array to tell if the buttons are correctly pressed. For the track, the car starts at the top in a box with a flap attached to a servo. when the code is entered, the flap opens, releasing the car down the track. The flag flipping mechanism uses a lever in the middle of the track attached to the same shaft as the flag. As the car passes over the levers, they flip down into the track, rotating the shaft and lifting the flags. This project is meaningful because it might be chosen to be part of an escape room, and solving the puzzle would give the people in the escape room joy and satisfaction.
