When i run the main.py file i get the error ''OSError: [Errno -9996] Invalid device''. I am new to all of this. does someone know what i need to do to fix this error?

Try to install portaudio, if you on mac brew install portaudio and install pyaudio pip3 install pyaudio for python3 or pip install pyaudio for python 2.x
Try to delete LightProject-master/Systematic-LEDs-master/python/lib/settings.ini and run again.

Having the same issue, running

pip3 install pyaudio

tells me requirement already satisfied (0.2.11), I also do not have a settings.ini file to delete, any thoughts?
