This project utilizes the following devices:

• Raspberry Pi Pico W
• Bottle of Crown Royal
• 2.5w speaker (pulled from an old laptop)
• PAM8302A 2.5w amplifier
• 0.5m of 5v WS2812B RGB LEDs, 15 LEDs total
• Some wood and hot glue

and software:

• MicroPython 8.2.9
• MQTT
• Adafruit IO
• Misc Adafruit libraries

to accomplish the following task:

• Allow me to send an alert to the device over the internet in order for it to play a specific noise and flash the LEDs a specific way, both similar and very dissimilar to an alarm clock.

Features:

• On startup:
  • Flash white 2 times to indicate the code is running and the LEDs are communicating
  • Connect to wifi in settings.toml
    • If wifi connection fails for any reason, slowly flash red 5x to indicate a wifi error
  • Begin cycling all colors slowly
• If command is received from Adafruit:
  • led_status_feed (not working)
    • ON / OFF
    • Not working - cannot think of a valid use case
  • shotty_time_feed
    • 0 / 1: begins shotty mode: plays a sound and flashes the LEDs simultaneously
  • brightness_feed
    • 0.3 to 1.0: sets the brightness. Default is 0.8. Resets on reboot
