Adafruit NeoPixel Addressable LED Sticks 8 x 5050 RGBW Adafruit 2867, The Adafruit NeoPixel Addressable LED Sticks have had an upgrade and now feature 8 x 5050 RGB Warm White 3000K LEDs. The white LEDs are very intense and add a new dimension to your NeoPixel projects with the 8 bit PWM you get 32 bits of colour. These seemingly simple gadgets have triggered an amazing array of creative projects, from watches and compasses to steampunk goggles and more. Each stick has solder pads for 5V DC and Gnd, plus data in and data out, using just 1 x GPIO pin on your microcontroller. Simply feed the data out from one stick into the data in of another to control them both from the same microcontroller MCU.Since the data protocol has strict timing requirements, the sticks are best controlled by a real time microcontroller such as the Arduino rather than a Linux board like the Raspberry Pi. Use an MCU with a clock speed of 8MHz or greater Arduino is 16MHz. Adafruit have published a driver library to save you the trouble and let you get on with designing eye catching displays. They have a reputation for the quality of their supporting documentation and you will find their Uberguide to NeoPixels and their Best Practices guides invaluable. In particular the Best Practices guide will help you prolong the life of your NeoPixels and avoid common mistakes. Please make sure you use the NeoPixel RGBW library, the RGB library will give odd results. Adafruit 2867 NeoPixel Addressable LED Stick 8 x 5050 RGBW Warm White 3000K
