- 3. In the broad sense, physical computing is a creative framework for understanding human beings' relationship to the digital world. In practical use, the term most often describes handmade art, design or DIY hobby projects that use sensors and microcontrollers to translate analog input to a software system, and/or control electro-mechanical devices such as motors, servos, lighting or other hardware.

- 4. An Open Source Physical Computing Platform It is a simple input/output board with a development environment.
- 5. Code on the Arduino IDE Upload that code to the Arduino Board Watch the Arduino Board run the code
- 6. int ledPin = 13; // LED connected to digital pin 13 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); // waits for a second }
- 7. The Digital Pins use a digital signal. Digital signals are either on or off. The Analog Pins use an analog signal. Analog signals can vary and are not stuck to being either on or off.
