NEO_RGBW Pixels are wired for RGBW bitstream (NeoPixel RGBW products) NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2) NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products) NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers) NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs) Argument 3 = Pixel type flags, add together as needed: Argument 2 = Arduino pin number (most are valid) Argument 1 = Number of pixels in NeoPixel strip How many NeoPixels are attached to the Arduino?Īdafruit_NeoPixel strip(LED_COUNT, LED_PIN, NEO_GRB + NEO_KHZ800) Which pin on the Arduino is connected to the NeoPixels? #include // Required for 16 MHz Adafruit Trinket A basic everyday LED Striptest program. We used 13 throughout this tutorial.Īlso make sure to adapt the strand size with the LED_COUNT variable. Please make sure to change your LED_PIN to the one you used to physically connect your leds.
