We discussed about our proof of concept; one of the 9 displays necessary for out completed project. It would require a stepper motor that would have a default state, and two displays; one for an "X" and one for an "O" that could be felt by the blind. Xavier decided to work on the programing of the TicTacToe program to run a stepper motor that would power the display, while I would design the display in Google SketchUp. I would implement out initial idea of cams to raise symbols in of the display
For our completed project, we would need multiplexers since there are not enough outputs nor inputs on the Arduino board to run nine stepper motors and receive inputs from nine buttons. We will have to solve this problem after our proof of concept.
