# 16 Feb 2023 - @todbot / Tod Kurt, from @studioStephe(she/they) post on Adafruit Discord
#
# Notes:
# - Glitches on first POST, but subsequent POSTs are glitch free.
# - Could get around this by muting mixer.voice[0].volume on first POST
# - Or could get around by doing throw-away POST before starting audio
# - The glitching appears to be related to DNS lookups?

# blinkm_simple_demo.py -- very simply demonstrate low-level BlinkM control
# 4 Jan 2023 - @todbot / Tod Kurt
#
# Note: BlinkMs are designed to be 5V devices, they may not work on 3.3V systems.
#       You should really use a I2C level shifter like: https://www.adafruit.com/product/5637
#       If you're powering many BlinkMs or a BlinkM MaxM, you *definitely* need a level shifter,
#       since you cannot risk sending 5V back to the 3.3V inputs of a CircuitPython board.
#
# Details of BlinkM protocol at http://thingm.com/s/BlinkM_datasheet.pdf
