I have decided I want to add a spectrum analyzer mode to my LED Top Hat. I have temporarily made an audio circuit for testing with an aux input. If and when I get the code perfectly right, I will put a microphone in the hat to capture the sound around it instead of aux input. This way, I can have cool, live animations based on the sounds around me. Overall, the code is coming along really well. Other than the spectrum analyzer mode, there is just some slight bluetooth communication issues to work out where it is unintentionally dropping bytes. I will be posting my code on github and writing a thorough tutorial once I finish the spectrum analyzer code and hat microphone modifications.
