Bulldog Google "adafruit slow flash led +.pdf" for a sheet to understand how these work. To allow endless color combinations use a 4 pin common cathode RGB led.

Q: In the speaking version, is there a way to turn off the sound?

Bulldog Yes you can. You need to hold down the black button marked "N L P" while you turn on the power by pressing the red button marked "select". The sound will be disabled for that session.
