Hello Forum Members,
I have been working on a portable speaker project that uses the teensy + audio shield to produce a light show. I have noticed two strange things today that are confusing.
1. When audio is hooked up to the teensy circuit for the light show sound quality is dramatically decreased. Lots of fuzzy distortion.
2. When audio is not hooked up to the teensy circuit, but the circuit is running, the lights still produce a FFT show when volume is super loud.. This was what has confused me the most. The amplifier is hooked up to 12v + ground on the bread board. The 12v is used to power a limiter circuit that sends audio into the audio shield. All grounds are connected but not Vcc. The mic is not the reason for this. I tested it with out the mic hooked up.
Im thinking that maybe some diodes might fix problem one but problem two is very strange.
Any ideas out there?
Thank you for your time,
Rex
