Free open-source cross-platform technology for animation badges, bike lights, eye-catching jewelry, wearables, and more. Animations can run in a simulator or on hardware with smart LEDs such as DotStars and NeoPixels.

Suitable for makerspaces aiming to teach coding concepts (including asynchronous multithreaded programming) to teens and adults. LED animations can be instantly viewed in the simulator after code edits.

Requires a Windows or Linux computer, Microsoft’s free Visual Studio Code editor/simulator, and the free open-source Glow IDE extension. No extra hardware is needed to get started, however the Elektra LED development board is available for hardware enthusiasts looking to run their animations on smart LED devices powered by an ARM Cortex microcontroller.

Follow the install procedure to get started. Also see this tutorial.
