  1. Marble Maze Team 20: Jordan Wagner

  2. Abstract iPhone controlled marble maze game Rotation of the phone is translated into rotation of the board Stepper motor connected to each knob on the board to control the x and y axis Data sent wirelessly and received with Raspberry Pi

  3. Overall Schematic

  4. Microcontroller Stepper motors are connected through drivers via two digital output ports each plus one for both enables (five total) Raspberry Pi is communicated with through UART, with one TX and one RX line Triple axis accelerometer uses three analog input ports for the axis readings and four digital output ports for enabling and controlling the device

  5. Microcontroller Schematic

  6. Triple Axis Accelerometer Image source: http://www.kerrywong.com/blog/wp-content/uploads/2010/09/lis3lv02dlaxis.jpg Each axis is a separate analog output Four digital inputs for mode selection and device control Used to determineorientation of game board and as feedback for motors

  7. Stepper Motors Each motor has a driver IC, which interfaces to the microcontroller Each driver will have a direction and step digital output, and both will have an enable signal

  8. Questions? Image source: http://www.amazon.com/Brio-34000-BRIO-Labyrinth/dp/B0001WGISK/ref=sr_1_1?ie=UTF8&qid=1360720104&sr=8-1&keywords=brio+labyrinth
