Tangible User Interfaces - Fall 2011

For this assignment I used some random pieces of household plastics (coffee cup and fruit container) to construct what was conceived as a 'disco ball' like effect. Using arcylic paint to black out the LED the light only shines through the holes, and those spots with less paint cover.

int potPin = 0;   // select the input pin for the potentiometer
int motorPin = 9; // select the pin for the Motor
int val = 0;      // variable to store the value coming from the sensor
void setup() {
  Serial.begin(9600);

void loop() {
  val = analogRead(potPin);    // read the value from the sensor, between 0 - 1024
  Serial.println(val);
  analogWrite(motorPin, val/4); // analogWrite can be between 0-255
