Expressive Pixels works great with MatrixPortal for LED animation
Create and display colorful animations using the Microsoft Expressive Pixels Application and display them on your Adafruit Matrix Portal! Microsoft Research’s easy-to-use app is a match made in heaven for the MatrixPortal, it takes only a minute to install the firmware on your Matrix, and then you can create, display and store animations right from the Windows 10 app, video.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound.
