Interactive Chinese Shadow, 2011<br />

Arduino Uno + Firmata + Firefly + TouchOSC<br />

Interactive Chinese Shadow is one <strong>of</strong> my final<br />

unit projects. It allows a participant to interact<br />

with a Chinese shadow device by using iPhone’s<br />

TouchOSC app.<br />

For this device, I used Touch OSC, an easy <strong>and</strong><br />

accessible independent interface for iPhone<br />

application <strong>design</strong>. This was augmented with<br />

Firmata, Firefly, Arduino uno, four servos, an<br />

RGB Led, a flashlight <strong>and</strong> a Chinese shadow<br />

toy. Firefly is a very easy-to-use s<strong>of</strong>tware that<br />

allow Arduino fans to achieve multiple functions<br />

without time factor <strong>of</strong> coding <strong>and</strong> Processing.<br />

The framework <strong>and</strong> 3D illustrations can help<br />

one more easily underst<strong>and</strong> the basic working<br />

process <strong>and</strong> how these s<strong>of</strong>tware <strong>and</strong> hardware<br />

connect <strong>and</strong> work together. Internal structure<br />

demonstrates what the device itself looks like.<br />

TouchOSC interface shows how the app works<br />

<strong>and</strong> controls the specific functions <strong>of</strong> device.<br />

This TouchOSC interface allows participants<br />

to adjust the device’s background colour,<br />

brightness <strong>and</strong> Chinese Shadow’s actions. Red,<br />

blue <strong>and</strong> green rotary-buttons control the RGB<br />

colour <strong>and</strong> the white rotary-button controls the<br />

normal LED brightness value. Four fader-buttons<br />

play the role <strong>of</strong> adjust Chinese Shadow’s actions.<br />
