Oh ha! Yeah i see AGND but i haven’t ever used it. I pretty much just have GND out to my breadboard ground bus and everything gnd goes to that. My pots and buttons work correctly. Whew got nervous for a minute 
It definitely makes a difference for more “sensitive” analogue components like my mic—the “noise floor” was reading about 700 when connected to the GND, 500 when connected to AGND.
Ill try moving my mic to it. Thanks
