I ripped apart a small Led Lamp (that you mount on head), which ran on two Coin cell battery. I was imagining, the circuit was as simple as wiring the Led to the Battery through a current limiting resisters.
But I was amazed by seeing some surface mount components and what appears to be a uC.
What funny might they be doing there?
