DVDdoug ; Ahhh thanks dude, maybe 10ms was a bit excessive I will test once I get a system working. And to my knowledge I can’t use a Bluetooth speaker, and still send data through the aux jack, if I am wrong then that’ll make everything so much easier , coz then I can use a shield like this SparkFun Spectrum Shield - DEV-13116 - SparkFun Electronics .
That MSGEQ7 seems ideal I’ll have a look, how would you separate each band if it’s multiplexed.
I have looked at FFT but it seems a bit over kill for what I need. And yes I am using 2 x 5m strips of rgb individually addressable LEDs.
Hats off to you sir, I wouldn’t dream of doing this without a micro controller
Question: if I use the 7 band audio analyser chip, would it possible to still , map a range of colours across the 7 bands
