ChronoArt sells a very nice BKC for $179 that I would like duplicate for personal use using an Arduino, with random colors RGB Fades, and tones Due to the construction of the clock face, each binary number would require 4 leds in unison except for the binary 1 for a total of 13 leds. I would like to use the Chronodot RTC and be able to set the time. I have a Mega2560 which provides the 13 PWM pins and with current limiting resistors would give the desiredeffect. However, I would rather use an Uno with multiple TLC5940 16-channel PWM chips daisy chained. Here is an image that explains the concept more fully. I have found a good binary clock sketch that I have adapted to the 4 pin (8-4-2-1) binary mode. I have adapted RTC, Fade , and Tone sketches, but I don't understand how the software converts the PWM pins thru the TLC5940 to the the RGBs. Could someone point me in the direction of/or write me a sample sketch that would accomplish this. I have looked at all the example sketches provided in the TLC5940 libraries but don't understand them. Any help will be greatly appreciated. Thanks
