Our earlier project Convert a Bunch of LED Strips into a Big Video Display explains how to build big and affordable hand-made video LED displays that connect to the Raspberry Pi, or any other computer with the standard video output, as an ordinary monitor and with absolutely no programming required to display any video content. The key component in that project is the open-source Pixblasters-Light FPGA based LED controller.
This LED controller enables easy control of up to 8, 192 RGB LEDs, RGB888 pixel format for 16M colors, integrated gamma correction and support for LED displays with resolutions up to 512 x 16 (H x V). Such LED driving capabilities already enables giant LED displays, i.e. 8.5 x 0.3 meters when built by 60 LEDs/m strip and monumental 17 x 0.3 meters when built by 30 LEDs/m.

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.
