12 LEDs have been used to create a simple mini lighthouse in which the beam rotates around the LEDs when applied with power. The project is featuring a full size ICSP connector and a socket DIP ...

Since the earliest versions of indoor LED light bulbs were developed, their designers have faced a variety of technical challenges. These include AC-to-DC power conversion, thermal design/heat-sinking ...

Light-emitting diodes (LEDs) are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the ...
