Schematics, Circuits inside of LED?
  • 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: ), but there are three separate LED elements (one red, one green, one blue), each with its own wire from the tiny integrated circuit.
