What about an RGB led?

By martinm, in New stuff, september 09,2011.

Building a USB device to drive the shy red led everybody knows would probably be a big overkill. At Yoctopuce, we are not really afraid of overkills, but there are some lines we are not willing to cross...

Anyway, driving one of these shiny little color leds might be more interesting: driving directly one of those is not so easy if you want to create the intermediate colors.
