Setup

This software needs certain libraries like PyQt4 and numpy, so the easiest way to make sure you have versions of everything that get along is to download a pre-packaged Python distribution. This software has been tested and works with WinPython 3.5.2.1 (not the Qt5 one)

• install WinPython-64bit-3.5.2.1 (not the Qt5 one)
• download this project and modify go.bat to reflect where your python.exe is
• build the circuit, plug it into your microphone hole, and run go.bat
