Firefly Jar SAO

This cute jar of twinkly fireflies is equipped with Rare Circuit's SAOv3 proposal. It's a common standard built upon I2C that enables badges and SAOs to do things like:

• Identify SAOs by vendor and product IDs
• Detect which port a SAO is connected to on badges with multiple ports
• Inform the badge of custom commands that can be used to control the SAO
• Support generic interfaces such as LEDs, that don't require any extra support between the badge and SAO

The SAO includes commands for various lighting modes, as well as support for the LED interface, allowing the badge to take complete control of the LEDs.

Maybe there's even a secret inside? Who knows. You'll have to play around with SAOv3 to know for sure.
