I have the proper 10uF ceramic cap on the way, I’ll get it today and test out the audio signal. Good to know the 4.7K resistors aren’t needed.
So the pots are linear? Would you say https://www.amazon.com/MCIGICM-potentiometer-assortment-Breadboard-Potentiometer/dp/B07C3XHVXV would work well and properly? Since the trimpots I got (such as these ones https://www.amazon.com/Variable-Resistor-Trimmer-Potentiometer-Assorted/dp/B07J4NR372) seem to work OK for updating the settings, but clearly not effective for the fine tuning during regular running.
Yes yes, CPU vs Microcontroller, I get it. I need to be a bit more precise in my terminology.
So https://www.microchip.com/wwwproducts/en/ATmega328? Which package/part #? I’m going to guess the ATMEGA328-AU as per https://www.mouser.com/Search/Refine?Keyword=ATMEGA328 pictures.
Thanks, I’ll keep that in mind for the future.
Let’s just say a direct connection isn’t workable. This is batter powered inside of a top hat. So a Mic is the only option, although I’m open to another mic type (MEMS, condenser) if it’ll be that much better. Which for my basic use case probably aren’t. I don’t need perfect fidelity, just something decent.
Hm, appears I can’t do a 2nd edit.
Ok, so…turns out somehow the LED count parameter had gotten changed. No clue, I didn’t do it. So instead I’ve changed it so all 3 60, 120, 180 are 36 LEDs. Now it’s lighting up quite a number of LEDs 🙂
So I have the https://www.adafruit.com/product/1063 wired up, GND to shield, Vin to the 5v input, Out to T & R. I’m seeing some LED reaction, but not much. The output is, at steady quiet room, 2.5v as would be expected (Vin/2), but it’s not all that reactive, even when there’s music with a steady beat going on. I’ve tried with the sensitivity all the way to the right, and tried changing the Parameter all the way to the right as well.
Thoughts? Ideas? Should I just say screw it and use the SparkFun electret you linked? Or is there any better mics that can be hooked up that don’t cost too too much? Or any code parameters I can modify to make it better?

Also, wonderfully easy to reprogram for custom number of LEDs! 🙂
