[sdiy] Coloured LEDs

[Vladimir Pantelic]

they can be driven just fine with no CPU overhead at all if you have a free
SPI and a bit of memory. not from a 'duino though but then it's 2017 after
all...

They’re quite processor-power hungry. As I understand it, the timing
requirements are very tight. If the control signals are generated by
bit-banging, the processor can’t do much else while LEDs are addressed.
Some processors have PWM outputs that can be mis-used to generate the
signals, but this looks like an ugly hack to me.
