Yes, if I jump to 5:30 I do hear beeps and audio. I assumed there was a spoken narrative walking through the steps from the beginning.

@Rongzhong Li Thanks, I'll do that.

Sure, thanks.

Thanks, I tried the Arduino Uno board setting but it didn't change anything. Still same error. Here's copy of error msgs from Arduino IDE and attached screenshot from IDE with that option: ------------------------------------- Arduino: 1.8.18 (Mac OS X), Board: "Arduino Uno" Sketch uses 444 bytes (1%) of program storage space.
