Official software for blink(1) USB RGB LED by ThingM
Eagle C# C Objective-C QML C++ Other


"blink(1) is a super status light: it packs three dimensions of information (color, brightness and pattern) into a single tiny package that fits into any USB port on nearly every device. It makes it incredibly easy to connect any data source in the cloud or on your computer to a full-color RGB LED so you can know what's happening without checking any windows, going to any websites or typing any commands."

The official repository of blink(1) software is:

That repo pulls from the active development repo:

Please submit any issues or pull-requests there.

Ready-to-run Applications to play with


Blink1Control is a GUI application for hooking events to blink(1) and is the primary user-level application for controlling blink(1). It is an event-based system for triggering blink(1) color patterns. Those events can be on your computer or on the Net.

Blink1Control can receive events from:

  • IFTTT's many channels
  • IMAP/POP/GMAIL email services
  • URLs containing text or JSON
  • Local files or executed scripts
  • Hardware monitors like CPU, battery, RAM

This verison of Blink1Control supercedes the Mac-specific and Windows-specific versions in the "mac" and "win" directories.
