Thanks to John for sending this in! John writes:
I build a alternative version of the Pimoroni Firefly Light project (https://learn.pimoroni.com/tutorial/sandyj/firefly-light) using the Adafruit Pro Trinket and a lot of other Adafruit parts.
I also built a companion project that uses three strands of LEDs and delivers a US 4th of July version at https://github.com/johnwargo/Arduino-Twinkle-Lights-Array.
The 4th of July and Christmas versions of this project use entirely Adafruit parts.
