What isphysical computing?

15

For Etsy 2011

Physical Computing is the digital meeting the physical.

16

For Etsy 2011

Through software and code, we can elicit analog and reactive responses from hardware.

17

For Etsy 2011

We can communicate between the computer and hardware, opening up greater possibilities.

18

Introducingthe Arduino

For Etsy 2011

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software.

20

For Etsy 2011

There are different types of Arduino, designed specifically for varying projects. They can be miniature, round, and flexible.

21

For Etsy 2011

The microcontroller on the board is programmed using the Arduino programming language, which is based on Processing.

For Etsy 2011

In simple terms, the code controls the output, allowing us to communicate between the computer and Arduino, opening up greater possibilities.

How is physical computing being used?

26

For Etsy 2011

Physical computing is being utilized by designers, artists, and technologists to create reactive and interactive products.

For Etsy 2011

There are several types of inputs: i.e. code, switches or sensors

34

For Etsy 2011

A switch is a device for making and breaking the connection in an electric circuit. This allows us to control when and how the hardware responds.

35

A switch completes the circuit, turning the output on or off.

Sensors allow for sensing of and responding to the physical world. This makes reactions from the hardware possible.

For Etsy 2011

Gesture and movement can be a mechanism for interaction through the use of cameras, the Kinect,and accelerometers.

The Kinect senses gesturesand movements.

For Etsy 2011

There are multiple outputs of physical computing, including light, sound, motion, and image.

What we’re doing today

51

For Etsy 2011

The Memory Bracelet

Creating a mechanism for aiding in memory

Code - will tell the Arduino when to alert us (i.e. every 5 minutes)

Arduino - will tell the actuator (led, buzzer, motor) to perform so we can see the effect

The bracelet - will be a casually wearable accessory acting as a host to contain this

mechanism

52

For Etsy 2011

Arduinos

Many types of Arduinos

for varying purposes

Today, we’ll be using the Uno.

Software

Manipulating outputs through code

by changing variables

54

For Etsy 2011

Outputs

Many different types of outputs

55

Light: LEDs Sound: Piezo buzzers

Motion: Piezo vibrator

Step 1: Wire

Step 2: Test

Step 3: Code

Step 4: Integrate

Step 5: Refine

Step 6: Use!

Potential Applications

Real-world applications for your bracelet include:

62

Alert to test blood sugar Reminder to get up and stretch Prompt to take medicine

For Etsy 2011

Extending the idea

Through hardware, sensors, and code

The next step would be to make this bracelet independent of the computer. We can hook it

up to a battery as a powersource and use smaller Arduinos such as the Lilypad to create a

free-moving memory bracelet!
