Hi, Recently I got a LED kit for experiments. Everything went fine,
but I would like to know the schematics INSIDE of those RGB and blinking LEDs. That would
be fascinating to know, how the LED is controlled. I can see the very
tiny black square inside….thanks for your hints.
There are quite a few of these things out there, each of which has different internal wiring. The basic idea is the same as found in our flickering LEDs (see here for pictures: http://www.evilmadscientist.com/2011/does-this-led-sound-funny-to-you/ ), but there are three separate LED elements (one red, one green, one blue), each with its own wire from the tiny integrated circuit.
