For those that don’t know blink(1) (also kickstarter projects - original and mk2), it’s a small USB dongle with just one (or 2 for mk2) RGB LED(s), that is programmable/accessible via an API and such (ifttt for example), so you can make it blink in specific colors, patterns and timing for different occasions, such as a mention on twitter, package arrival, etc…
Since it’s “just” an RGB LED, I thought about creating one myself, using the Spark Core and its colorful LED (or just an RGB LED).
Anybody has an idea on how should the firmware work ? Exposing a method for each characteristic (color, delay, smell ) ?
I’m pretty low on ideas about how to do it, so any advice or idea would be awesome!
