Big Ball Maze Game with ArduinoAugust 24, 2012

"This project was the result of an urge to contribute something to the Creative Games section of my kids’ elementary school fair. The kids loved it for it’s simple old-school game aesthetic mixed with Wii-style and Kinect-style video game control. It’s a spin-off project of an earlier Ball & Plate experiment mentioned here in the Instructables forums.

The machine is an over-sized (1200mm (48”) diameter) version of the traditionally hand-held game where the object is to tilt a circular disc to move one or more balls though to the center of a maze. The circular board is supported by a stand with a centrally mounted gimbal, and controlled by either a wired hand-held contoller, an Android phone, or by body movements.

An Arduino microcontroller is used to monitor the player's actions and then adjust the tilt of the board to match. The wired controller uses an accelerometer module. The Android phone controller uses the in-built accelerometer and a custom app made with Processing to communicate via bluetooth with the Arduino. The body controller uses two sonar proximity sensors to detect how far the operator is from a central position to determine how much to tilt the board.

The board is tilted using two gearmotors pulling on strings attached to the underside of the board – one for front and back, and one for left and right. An accelerometer is attached to the underside of the board to provide the position feedback to the Arduino."
