Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

I have spent at least an hour almost every day since the 80’s advancing my knowledge in electronics. Recently I brushed up my knowledge on LED fading secrets and attained something pleasant. Now, I’d ...

The IS32LT3959 is a single inductor, multi-topology controller with constant on-time for driving a ground referenced high-voltage LED string. This single channel switching LED driver integrates a PWM ...

[Dave] needed some extra light above his desk/workbench area and decided to wire up some RGB LED light strips to brighten the place up a bit. He wasn’t content with using a standard switch to toggle ...

Usually, an MCU is considered a digital device. By default, its output voltage level can be either high or low and nothing in between. With the requirement to create an LED brightness control, the ...

LEDs in automotive interior and exterior lighting devices that implement a simplified driver IC design can have their brightness intensity adjusted depending on the scenario. The automotive industry ...

This module introduces Pulse Width Modulation (PWM) techniques for Python on the Raspberry Pi. Subsequently, by using PWM we can modify the brightness of an LED without having to change a resistor.

Community collaboration is a great thing. Take the Arduino PWM library for shift registers. Some folks at the Arduino forum pitched in and helped [Elco] trim off a bunch of clock cycles by using the ...
