Tangible User Interfaces - Fall 2011

My homework is a video game in which a potentiometer and force sensor are used to control a space invaders like scenario.

When the game ends the motor turns to provide a jarring physical feedback. (kindof)

 

Game code was found online, and adapted to work with arduino board input/output.

 

/* Physical Pixel

 

 An example of using the Arduino board to receive data from the 

 computer.  In this case, the Arduino boards turns on an LED when

 it receives the character 'H', and turns off the LED when it

 receives the character 'L'.

 

 The data can be sent from the Arduino serial monitor, or another

 program like Processing (see code below), Flash (via a serial-net

 proxy), PD, or Max/MSP.

 

 The circuit:

 * LED connected from digital pin 13 to ground
