    Intro

    SoundPad

    This is the first recipe of the InstantSOUP series. It’s something you can try out before you get your Wiring board. In this recipe we will build a sound toy with four pads. Pressing each pad will produce a different sound. We will be using a repurposed computer keyboard, replacing the keyboard keys with another kind of input.

    Repurposing computer keyboards is an easy and effective way to dive into physical prototyping. Also, it’s probably the least expensive way to begin experimenting! Keyboards are useful because many kinds of software can be controlled with keyboard input. We can build a physical interface that doesn’t look like a keyboard, and still pass keyboard commands (keystrokes) from it to Flash. This technique has been used at Interaction-Ivrea in a number of interesting projects.

    What you will learn

    How to use the internal microcontroller of a keyboard instead of a real microcontroller to get an instantly satisfying physical interaction.
    How to replace keyboard switches with switches of your own.
