This RGB based LED ring is the second version of a project which has three LED driver chips which enhance the brightness of the color lights. I found the second version more appealing than its ancestor when I watched the video. The first version used only one LED driver IC which was less attractive than this one. If you want to give this cool RGB based LED ring a try then you can refer with the whole procedure described below by Robert here.
“As of ’۲٫۰ beta’ (likely to become the final version) it comes with 3 dedicated constant current LED driver chips (MBI5168), which completely avoids multiplexing the LEDs and boosts brightness again. Color balancing is done entirely in hardware using 3 potentiometers. The hardware differences should be taken care of in the core part of the demo code, ‘User-land’ code is mostly the same”.
