The Pendulum Challenge Kit from the Maker Shed includes everything you need to make the project featured in Make, Volume 26. At the heart of the system is a pre-programmed PIC micro controller that runs the internal state machine which processes the game’s switch inputs and drives its LED outputs. The game’s most distinct feature is its array of 15 LEDs (14 red and 1 green), arranged in the shape of an arc to simulate the path of a swinging pendulum. For added sound effects, the game has a piezo buzzer.
