This was the issue. All solved! Thank you for making this Andrew!

Here is a video for reference. Thank you in advance!

So, the Basic will "work", but it doesn't have enough disk space for any of the audio files😅

Okay! It should work based on the specs, but ill keep you posted. Half the fun is experimentation after all!

I looked up the specs and the only difference appears to be the express lacks EEPROM. I'm new to the electronics part of this hobby. I have a basic knowledge of computers and coding (high school level) but have apprenticed for an electrician for a few years. So, basically, I'm having trouble tying everything together 😅 Sources: Express: https://learn.adafruit.com/adafruit-feather-m0-express-designed-for-circuit-python-circuitpython Basic: https://learn.adafruit.com/adafruit-feather-m0-basic-proto
