Hi again. I was testing out the line-in jack on the sensor expansion by loading the “sound - spectrum analyser 1D/2D” pattern (and taking out the demo portion of that code). While the microphone reacts to sound, but it is very noisy, and reacts to the noise the PixelBlaze itself is emitting (see my other post).
When plugging a cable into the line-in jack - with nothing attached at the other end - the pattern is quiet and isn’t jumping around. However, if I then plug it into a low-volume speaker output on my computer all heck breaks loose. The pattern reacts to sound that isn’t playing and can’t “hear” anything that is playing.
I’m currently not able to use the sound input for anything due to the noise on either of these inputs. Please advise?
