The PIXEL kit from LED:ART consists of an RGB LED matrix, a IOIO Mint Bluetooth microcontroller to drive the matix, and some software to give instructions to the IOIO for what to display.
Originally, only an Android and PC based software was available. Now, web based controls are available, via a Java application. Web based controls means that platforms with a modern browser are supported; iStuff, Android, PC, Tablet, and others. The Web applicaion is started from the command line.
Being able to run from the command line allows for use as a background service/daemon. This approch is also ideal for setting up headless envronments (no monitor attached to the mother board), where the hardware profile needs to be as slim as possible.
PIXEL comes pre-bundled with some still and animated images. On first run, the images are extracted to pixel/ under the user’s home directory.
Once the hardware is assembled, and the software running, the PIXEL Web controls are availble to any computer on the same network as the Raspberry Pi.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
