We’ve all been taught to believe that was an RGB source such as a NeoPixel or the RGB pixels on your computer monitor or flatscreen TV you can make any color you want. But it turns out that our concept of “Brown” is a different thing. It all depends on context. In this fascinating video from Technology Connections they explained that Brown is actually a human construct that is not among “the colors of the rainbow” and is virtually impossible to create with RGB LED such as a NeoPixel.
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.
