A timer-controlled doorbell device has been developed using two 555 timer ICs in monostable mode, combined with a relay ...

Repurposing Industrial Input Chip into LED Driver This LED driver circuit is based on repurposing an industrial digital input chip for a function different from its originally intended application.

The RGB LED driver circuit is crucial for adjusting the lighting colors and intensity. It is designed using a 3-channel transistor setup, with four sets of RGB LEDs connected in parallel.

This approach can greatly reduce system complexity for the driver circuit arrays while maintaining device opto-electronic performance. In this work, we demonstrate a 3-terminal GaN micro-light ...

Vishay Intertechnology, Inc. has introduced a new automotive grade photovoltaic metal-oxide-semiconductor field-effect transistor (MOSFET) driver as the first such device to offer an integrated ...

In this short tutorial, we will show you how you can build yourself a transistor-driven color-changing RGB LED lights. The building process is simple and requires only a few transistors, capacitors ...

In this paper, the minimum bit depth of drivers for active-matrix light emitting diode (AMLED) displays has been specified to overcome luminance nonuniformity of LEDs for the first time. The pixel ...

[Petteri Aimonen] created an omnidirectional LED safety light to cling to his child’s winter hat in an effort to increase visibility during the dark winter months, but the design is also grea… ...
