How It Works

The LED strip shows the current game state with color-coded feedback. When it's tied, you'll see purple lights. As one player gains advantage, the colors shift to red or blue. A servo motor moves the joined arms based on button presses, creating a realistic arm wrestling effect.

When someone wins, you get victory sounds and flashing lights before returning to the idle state for the next round.
