Voltage regulator ICs (78xx series) provide a steady output voltage, as against a widely fluctuating input supply, when the common terminal is grounded. Any voltage about zero volt (ground) connected ...

Here, we have explained about the circuit that automatically controls the intensity of street lights which is designed using microcontroller and LEDs. It is very useful to save the power. Street ...

The big picture: Researchers from the University of California have developed a first-of-its-kind, solid-state thermal transistor that could one day be used to better control heat in electronic ...
