Hi again, I am facing another problem. I have 2 LED Strips, one Cotrolled with WS2812 Controllers and one ordinary RGB Strip controlled directly with the Arduino using a FET Shield. I am using the HSV to RGB function of FastLED to generate a smooth fading effect. The problem is, with the digital strip this is working perfectly and looking really nice, but the FET controlled strip looks really crap at the color red. I have made a video to show the difference. On the left is the digital RGB strip, on the right the ordinary strip. Does anyone have an idea how i can adjust the color?
It looks to me like (as is often seen) the green LEDs and blue LEDs on the analog strip are almost 2X as bright as the red ones.
You can’t make the red brighter, but you can balance the color: try dividing the green (and possibly the blue) by a factor of two as a starting point, and see if that looks more balanced.
And by the way: GREAT video showing the symptoms. Really helps make it clear what’s going on!
Well… Also (updated) it looks like the analog strip in the video has about half as many LEDs per foot as your digital, so it’s going to be less bright overall.
As for color balance, every LED strip is a little unbalanced: it’s because green LEDs are inherently brighter (because atomic physics!) then red. Blue can go either way.
The key is finding out the right color balance for the strip you have!
