Typical NeoPixels have LEDs which each have three colours: red, green, and blue. RGBW NeoPixels have four LEDs per pixel: red, green, blue, and white. Why add an extra white LED? Can’t we make white just by mixing red, green, and blue? Since “white” isn’t a colour by itself, but Read more…
NeoPixels are LEDs that can be programmed to show specific colors. They are connected serially, allowing long chains of them to be easily controlled. You connect the first NeoPixel to a data output from your CircuitPython board, and each additional LED is connected in a chain. Pre-wired strips, rings, and Read more…
