****************** COLDFIRE ELECTRONICA *******************---->> PRODUCTO COMPLETAMENTE NUEVO, SELLADO EN SU EMPAQUE.** PRODUCTO DE ALTA CALIDAD, FABRICADO EN USA POR ADAFRUIT, NO CHINO ! ** Los NeoPixels son originales de Adafruit y son diodos LED RGB de tipo 5050 con un controlador WS2812 integrado. Existen en varios tamaños y formas y tienen una amplia documentación, tutoriales, así como librerías listas para utilizar con Arduino. Es extremadamente fácil ponerlos a funcionar en pocos minutos ya que tan solo necesitan un pin, ofrecen potentes y brillantes colores!Make your own little LED strip arrangement with this stick of NeoPixel LEDs. We crammed 8 of the tiny 5050 (5mm x 5mm) smart RGB LEDs onto a PCB with mounting holes and a chainable design. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC (4-7V works) and you're ready to rock.The LEDs are 'chainable' by connecting the output of one stick into the input of another - see the photo above. There is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microconroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the netduino or Basic Stamp. Our wonderfully-written Neopixel library for Arduino supports these pixels! As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please google around. An 8MHz or faster processor is required.Comes as a single stick with 8 individually addressable RGB LEDs assembled and tested.** Se pueden unir varias barras para armar una una tira de neopixel mas grande, por la parte de atrás se pueden hacer puentes con soldadura fácilmente ( en el tutorial de Adafruit indican como hacerlo ).Dimensions: 51.10mm / 2" x 10.22mm / 0.4" x 3.19mm / 0.12"Weight: 2.57gMay ship with either WS2812B or SK6812-based LEDs. They are the same brightness, color and protocol** INCLUYE TUTORIAL, LIBRERIA Y EJEMPLOS CON ARDUINO HECHOS POR ADAFRUIT ( pdf en ingles ).
