Arduino Electromechanical Box

This was a fun one — I built a box with a switch on it that, when you flip it, doesn't just respond normally. Using Arduino and a state machine, I coded in different "tricks" so the box might pause for a second, oscillate back and forth, or throw out a random response instead. The mechanical side (motors, switches, wiring) had to work with the code, so getting the timing to feel natural instead of janky took some trial and error. The state machine logic is what made it possible to have all these different behaviors without the code turning into a mess of if-statements. It's not a practical project, but it taught me a lot about how to actually structure code for something that reacts to the real world in real time.
