By Design Library (Contributed Content) Sunday, Jshares. Aspencore Network News & Analysis News the global electronics community can trust. Adafruit has the Adafruit Neopixel Uberguide that is a complete and detailed source for all possible questions and concerns dealing with addressable LEDs. chipKIT Pi (designed for Raspberry Pi) is the latest Arduino® compatible chipKIT platform from Microchip and element14.I also strongly agree but haven't used a resistor out of convenience and/or laziness. Adafruit strongly suggests adding a resistor about 470 ohm between the microcontroller data line and the LED data pin.

10 -15 LEDs at low brightness can be ran off of the microcontroller directly but either high intensity or higher numbers of LEDs can cause too much current draw for the microcontroller and an external power supply is required.WARNING - I am not responsible for damage caused to your LEDs by not heeding the following warnings! the PICxel library (also covered later).addressable LEDs (WS2812 or WS2811) I soldered female headers to the strip.Going through through a couple steps will allow your to get started with the PICxel library. There has not been a simple addressable LED library for PIC32 microcontrollers until now! The PICxel library is an MPIDE library that handles the timing required to use addressable LEDs (WS2812, WS2811) or more commonly known as Adafruit Neopixels.
