NeoPixel ring - 16 x adresserbare RGB LED m. drivere
Varenr:
H34488
EAN:
5705412344883
16 stk. lysstærke smart LED NeoPixels er arrangeret i en cirkel med 48mm ydre diameter. Ringene er 'kædelige' - tilslut blot udgangsstikket på en til indgangsstikket på en anden. Brug kun en microcontroller pin til at styre så mange som du kan kæde sammen! Hver LED kan adresseres, da der er en driverchip inde i LED'en. Hver enkelt har ~ 18mA konstantstrøm drev, så farven vil være meget konsistent, selvom spændingen varierer, og der kræves ingen eksterne choke modstande. Strømforsynes med 5Vdc (4-7Vdc).
Der er en enkelt datalinje med en meget timing-specifik protokol. Da protokollen er meget følsom over for timing, kræver den en realtids-microcontroller såsom en AVR eller Arduino. Den kan ikke bruges sammen med en Linux-baseret mikrocomputer eller fortolket mikrocontroller som netduino eller Basic Stamp. Der kræves en 8 MHz eller hurtigere processor.
Leveres som en enkelt ring med 16 individuelt adresserbare RGB LED'er samt ledning med stik for input og for output (loop). Du kan blot afmontere output-ledningerne, hvis du ikke bar brug for dem.

16 ultra bright smart LED NeoPixels are arranged in a circle with 44,5mm outer diameter. The rings are 'chainable' - connect the output pin of one to the input pin of another. 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.
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 ring with 16 individually addressable RGB LEDs assembled and tested.
