Marble MazeTeam 20: Jordan Wagner

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

Overall Schematic

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

Microcontroller Schematic

Triple Axis Accelerometer 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

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
