Firefly

ADDON. Version 1.0.0.70. Released on 2015-Mar-25. Provides 88 components. Created by Andrew Payne (LIFT architects). Features 23 video tutorials.

Firefly is a set of comprehensive software tools dedicated to bridging the gap between Grasshopper (a free plug-in for Rhino), the Arduino micro-controller, the internet and beyond. It allows near real-time data flow between the digital and physical worlds, and will read/write data to/from internet feeds, remote sensors and more.

Utility

	Binary Blink (Blink) Oscillates 0's and 1's based on an incoming pattern of integers
	Buffer Store the last number of values based on the buffer domain
	Constrain Constrains a number to a specific numeric range.
	Data Log (Log) Create a log of incoming data.
