Confirmation that the INK1003 chipset works

Now that winter is in full swing, I’m back to working on my indoor projects. One of those involved using an INK1003 based digital RGB LED string with the Arduino and FastLED which I mentioned in an earlier post.

Today I finally got around to building a power-supply and breakout board and I tested the string with both FastLED and Adafruit’s NeoPixel libraries. It works perfectly with both.

Here’s the setup string I used in my sketch.
FastLED.addLeds<WS2811, DATA_PIN, RGB>(leds, NUM_LEDS);

I ran the FirstLight sketch 4 times, swapping in “Red”, “Green”, and “Blue” for “White” in the original sketch successively. Every variant worked so that also confirms the RGB layout of the LEDs.

I’m going to put together a post detailing everything I did, including how I wired and powered the Home Depot INK1003 based LED string, but I’ll do that tomorrow as it’s pretty late and I’m going to bed with the smile of success on my face.

Thanks to everyone that offered help and suggestions.

at 0343? huh…I thought I was the only one soldering until the wee hours…but I only made it to 0130…I’m taking my fake server light controller and making more sexy rack mount box for the controllers

christopher. Did you ever put together that detailed post? I for sure would be very interested knowing how you solved this, since I just happened to buy some meters of that strip…

@Daniel_Linder Sorry, I thought I had, but I’ll look back and post one if not.

Hi Christopher, i have a ink1003 strip too but i have some issues on controlling it. How did you solve the cablage problem?

@Luca_Sommaruga
cablage problem? Can you expand on that?
