Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor ...
This article proposes a three-phase resonant driver based on the resonant switched capacitor (RSC) for the light emitting diode (LED). The employed LED is chip-on-board (COB) based technology, ...
High-brightness light-emitting diode (LED) is next generation of green lighting. However, the bulky electrolytic capacitor is required to compensate the difference of pulsating power, thereby ...
