<div style="RIGHT: auto"><SPAN style="RIGHT: auto">If you go to the Adafruit website and look at their material on addressable LED strips you should get some clues. You basically use PWM to control each LED...the kind of chip will dictate whether you need to keep sending the signal or just send it once and the chip will keep PWMing until you change something.<VAR id=yui-ie-cursor></VAR></SPAN></div>

<DIV>I picked up a Christmas light at walmart and trying to find info about it. What interested me is that for $8 I got 15 RGB LEDs, each with it's own little pcb and it seems like they can be controlled individually! Of course it's not as simple as reading the specs because I haven't found any (did google the numbers found) and the IC is a black blob so no help there.<BR>I opened up the first and last one to take some pictures. The first one has 5V feed on the upper row marked "DI", the bottom row marked "DO" has 3 wires going to next light where it comes in on the "DI" row, out on a "DO" and my guess is that it goes on like that to the end.<BR>I took some pictures of it that can be seen at http://flickr.com/gp/henahadu/73436S/ <BR>My question is - anyone seen anything like it ? Any clue on where/how I can find more info? Somewhere else to ask ?<BR><BR>/ps<BR><BR><BR><BR></DIV></DIV><BR>_______________________________________________<BR>Lab mailing
