hi.i want to control a 12v multicolor led strip i bought locally with my arduino uno, i have seen tutorials for neopixels but they dont work with my led strip its from "LED´s light" and it has 4 ports : "+12v" "di" "-" "gnd" i have lso tried to control it using fast led but that dosnt work aswell the strip is segmentd in segments with 3 leds and a chip and also some smaller parts that i dont know(picture)
thank you for your help
Please post your schematic that show powering the leds and the arduino.
Do you have any details about led strip? Is it ws2812a/b or 2815?
May be chinnese analogs like 6812?
The labeling implies:
"+12v" Connect the +12V supply here
"di" Data In. Connect the output pin of the Arduino here
"-" Unused?
"gnd" Connect the Ground side of the +12V supply AND the Arduino Ground to here.
If you get the wiring right I would expect the NeoPixel or FastLED library would work.
Are there any markings on the LEDs that would help to identify them?
Hi,
from your description and photo, it looks like this tape uses the LPD6803 chip.
There is a library to use with Arduino and this tape.
