Blink1Control2.3.0

Blink1Control lets you turn a blink(1) USB RGB LED into an at-a-glance status light, so alerts can reach you without keeping a computer window in view. It gives color, brightness, and pattern meaning to events from your computer or the internet, making a small light useful for notices you might otherwise miss. The blink(1) mk3 fits into a USB port on nearly every device and presents those signals through a full-color RGB LED.

Notifications can be driven by cloud data through IFTTT.com, email, monitoring URLs, or your own scripts. Server administrators and people running headless computers can use the blink1-tool command-line program, while developers can connect through C or Python and use Linux kernel support. Typical uses include server monitoring, online or away indicators at a cafe, and other situations where a colored light is quicker to notice than checking windows or typing commands.

Blink1Control also provides a getting-started experience for Mac and Windows users, while this release targets MacOS. Version 2.3.0 is built for Apple Silicon (arm64) and requires a blink(1) USB light device to produce notifications. It is freeware, and the blink(1) software family is open source, making the application suitable for interactive desktop use as well as automated developer and server workflows.
