In this video, the author is going to show how to use an LM317 to build a constant current driver for LEDs and laser diodes.

In this tutorial we will not use any dedicated driver ICs, but we will make a 2.5 Watt AC LED driver circuit using basic components.

In this step-by-step tutorial, we're diving into the world of electronics and microcontrollers to create a personalized 8 by 8 LED matrix that can be controlled using an Arduino board ...

In this tutorial, you will write a driver that runs on the L432KC Nucleo microcontroller which can interface with the MCP23017 GPIO (General Purpose Input Output) expander via the I2C communication ...

The major problem with the traditional high power AC to DC switching LED drivers is the power loss associated with it. These traditional AC LED drivers use switching topologies and resistors to ...

Although a single-stage off-line power LED driver can achieve low cost and high efficiency, the notorious double-line-frequency flicker issue with a single-stage LED driver limits its usage in ...
