Physical Computing

Physical Computing is an approach to learning how humans communicate through computers that starts by considering how humans express themselves physically. In this course, we take the human body as a given, and attempt to design computing applications within the limits of its expression.http://itp.nyu.edu/physcomp/(ITP is a two-year graduate program located in the Tisch School of the Arts)

// Blinking LED // by BARRAGAN

int ledPin = 0; // LED connected to pin 0 void setup() { pinMode(ledPin, OUTPUT); // sets the digital pin as output } void loop() { digitalWrite(ledPin, HIGH); // sets the LED on delay(1000); // waits for a second digitalWrite(ledPin, LOW); // sets the LED off delay(1000); }

Sensors, Actuators
