Here is one simple circuit of a general-purpose white LED security light with Passive Infrared (PIR) Motion sensing mechanism. At the heart of the circuit is a PIR sensor module SB0061. SB0061 is a ...

A modern LED flashlight, on the other hand, includes a little circuit board that consists of a current regulator and a microcontroller. Yes, you read that right: we live so far in the future that ...

This design describes how to light a string of LEDs of any color from a 1.5-V cell using just a few inexpensive components. The circuit (see figure) forms a self-oscillating, unregulated step-up ...
