Lab 5 - DJ Gloves
Description
The goal of this homework is to integrate inputs and outputs into an embodied interface. I used a Piezo speaker, light sensor and force sensitive resistor (FSR) all connected to my breadboard.
DJ's these days have been known to spin records, false records connected to iPods, and just press buttons on iPods during their sets. Well not anymore. Now DJ's can use the DJ gloves to change songs while rocking out.
I used the FSR sensor inside one glove to change the notes played on the Piezo. I also used the light sensor to alter the output when you press the FSR all the way.
