In this final part of the series, we’ll build our new interface for musical expression. I’ve included two options, one is a basic potentiometer (like we saw in the first part of the series) and the other combines the potentiometer with an LDR. In the videos I cover both options.

Warning: the second option requires a bit more data transformation than we are used to. This is because we have to separate our two values (ldr and potentiometer) by a comma, and then ‘store’ those in separate lists to access in Unity.

In both cases, we’ll be doing the following:

Unity Tutorial Series: Audio


In this week’s tutorial series, I’ll introduce the basics of Unit’s audio systems, with a particular focus on 3D audio and what sets it apart from simple (boring) 2 channel stereo.

Specifically, we will cover:

  • An introduction to audio in Unity
  • Creating New Interfaces for Audio Expression

The Project

The inspiration for this week, comes from a surprisingly neat performance I found when searching for instruments that would lend themselves well to our physical (arduino) and digital (Unity) platform. I naturally, thought of the theremin.

The theremin is was invented in 1928 by Leon Theremin and consists of two antennas that sense the relative position of the hands and control frequency (pitch) with one hand, and amplitude volume with the other. …
