WS2812B 5050 RGB LED Strip 5V DC. Denne LED-strimmel er lavet af WS2812B LED’er, der er forbundet i serie. Disse LED’er har en IC indbygget. Dette gør det muligt at kommunikere via en ledningsgrænseflade. Det betyder, at du kan styre den alle enkelvis ved hjælp af kun en digital pin på din Arduino, eller and form for board. Det er også muligt at klippe strimlen over og samle den med noget at de monterings vinkler vi har, dem kan du finde HER.

Installere Arduino IDE Software
Før du kan starte din programmering skal Arduino’s IDE software hentes. Dette program bruges til at programmere chippen.
Download fra dette link: Download
Installere FastLED Library
- Download library (Download)
- Udpak filer
- Flyt/kopir mappen “FastLED-master” til “libraries” som findes i “Arduino IDE” mappen (C:Program Files (x86)/Arduino/libraries)
- Åben Arduino IDE software og klik på “Sketch/Include library”
- Klik nu på “Add Zip. library” og find Zip filen du lige har downloaded.
- Åben “Sketch/Include library/Manage Librarys” for at opdatere library.
- Luk, og åben Arduino IDE programmet. (Genstart programmet)
- Nu er “FastLED-master” installeret
Programmering
Inden programmeringen kan udføres skal den rigtige “COM” port findes. Klik “Værktøj/Port” – og vælg COM port.
Eksempel
Her viser vi et hurtig eksempel på hvordan du får LED stripsen til at vise forskellige farver.
Du skal bruge:
Forbind sådan:
- Arduino “GND” -> LED Strips “GND/Hvid”
- Arduino “Pin 5”-> LED Strips “D0/Grøn”
- Arduino “5V”-> LED Strips “5V/Rød”
Info: De 3 ledninger “Rød=+”, “Hvid=GND” og “Grøn=Signal”.
