Fun with RGB LED Strips - Part 9: Full Reel Revisited

My power supply came today (a TDK-Lambda LS200-5, $58 from Mouser), so I was able to try out the full 5 m strip at full brightness. These suckers are quite impressive! Unfortunately, my DMM has a 10 A limit for current, so I'll have to take things into work with me one day to measure draw.

When firing up the strip at full brightness for the first time with the new supply, there was a noticeable loss of output toward the unconnected end of the strip. The way I'm powering the strip through a breadboard may be part of the issue, though I've seen reports of similar behavior online. For now, I've got supply and ground connected at both ends and performance is just fine.

Another obligatory video follows. Hey, at least it's not my dog. Well, it wouldn't be my dog, since I dislike dogs and don't own one... but you get the idea...


Sadly, playtime's over. I now have no excuses to avoid digging into audio. Oh well... It'll be fun once the code's done. :-)

  1. Hi, I tried to write the code based on your method. I can't seem to get it working though. I don't have an oscilloscope and hence can't look at the signal. Is it possible to provide the code?
