Neopixel Strip

Post by kglasnapp »

Order Number : 1565091-3953629129

Message : I ordered 2 -- Adafruit NeoPixel Digital RGBW LED Strip - White
PCB 60 LED/m PID: 2842. It came as a 2 meter strip. The strip does not seem to work. I have validated my software
and the ardunio controller on on a 8 Neopixel strip and it worked correctly.

I tried both:
Adafruit_NeoPixel pixels = Adafruit_NeoPixel(NUMPIXELS, PIN,NEO_GRB + NEO_KHZ800);
Adafruit_NeoPixel pixels = Adafruit_NeoPixel(NUMPIXELS, PIN, NEO_GRBW + NEO_KHZ800);
Neither option worked with the string.

Can you show the actual connection to the strip with the first few pixels. Make sure you are feeding into the input side of the strip.

Thanks so much. I connected the control signal on the terminal block thinking that was Din. Din was on the other end. Once I connected to Din the strip worked correctly.

Another question, I accidentally connected 12 volts to another strip I had. Do you suppose that all of the neopixels got destroyed?

You can test the strip and see. If it doesn't work you can cut the first pixel off and try again.
