Fun with the MSGEQ7 Graphic Equalizer Chip

Not much today. Just a pair of videos from some testing I’ve been doing with the MSGEQ7 Graphic Equalizer Display Filter chip. The first one shows the waveform of the analog output of the chip.


The second video shows what happens when you take that output and parse it out to a bunch of LPD8806 lights.


If these experiments go any further, I’ll do a more in-depth post with code and schematics and stuff. If you have any questions, please let me know in the comments below 🙂
