Without this, if the LED turned red during my program, it stayed red on reset, even though my setup code was initializing it and turning it off. It was very odd and almost random. Only happened when the LED was RED on reset, and seemed intermittent. Very strange, I am still not sure what was going on.</p> kewakl urn:uuid:3eabd9ca-54be-8a2b-7fce-5eb93da8748a 2016-06-20T16:37:47-06:00 <p>With pot legal in Colorado, it MUST be interfering with updating datasheets and product descriptions!</p> Customer #134773 urn:uuid:d9a24def-c1e0-0d5f-f902-93287985827c 2015-12-02T23:05:43-07:00 <p>OK, I <em>finally</em> got around to trying them.

A WS2812 is the name for a LED with the driver built in. So you are some what correct. However, I do believe this would still fall under a 2812 as it has the LED attached.</p> Orladin urn:uuid:d949c21e-e444-79ff-5e0c-360b266de416 2015-09-27T21:31:44-06:00 <p>Anyone have any information on the brightness of these (mcd)?

The Latch signal (50 usec low) is at the end of the data string, not between the 24-bit sequence for each LED. If you leave too much time (> ~5 usec) between 24-bit data, the 1st LED thinks it is at the end of the string and never passes the data through using DO. We need at &lsquo;real&rsquo; datasheet with actual pinouts, timing diagrams, electrical characteristics for the DO line, etc!</p> Customer #1250 urn:uuid:7ad98e52-ee23-18e8-52fa-29919e0bff0d 2014-08-17T11:29:45-06:00 <p>I didn&rsquo;t have any trouble getting the 1st LED in a string to work by bit-banging with a PIC, but I&rsquo;m getting no signal from the DO pin. So, the 1st LED changes colors, but the subsequent LED&rsquo;s in the daisy-change are blue (the start-up color). I tried disconnecting the 1st LED, pulling it up with a 1k resistor, but this just gives a DC voltage to rise from ground to ~2V. Maybe I have a defective batch? I tried switching other LED&rsquo;s into the 1st position with the same result.

But basically each led takes 24 bit color information (RGB) and you send out 24 bits x however many LEDs you have chained and the IC removes its color data and forwards the remaining to the next in line. There are very specific timings needed but its doable with arduinos.</p> OhmMyGadgets urn:uuid:25787181-a779-fcba-8f44-1c60e473eef8 2014-07-18T10:23:20-06:00 <p>Are you looking to project mixed light? The clear-lensed RGB LEDs I&rsquo;ve seen so far tend to splay the different colors. Since each color comes from a different die, they can&rsquo;t all be located in the center of the epoxy. So, on the clear RGB LEDs I&rsquo;ve seen, one color will project straight, but the other two will be at a slight angle.</p> xtopher urn:uuid:9bd4313a-2f93-6e31-4d4c-ce5b9f4fdc56 2014-07-18T09:56:14-06:00 <p>Yeah, the DS that we have gotten from our supplier is not good at all.
