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 ...

An RGB LED module is a versatile lighting component that can produce millions of colours by mixing red, green, and blue light ...

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 ...

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 ...

Most of us are aware that charlieplexing can drive a large number of LEDs from a relatively small number of I/O pins, but [David Johnson-Davies] demonstrates adding another dimension to that method to ...

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 ...

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 ...

The GALT61120 is an analog-enhanced ASIC chip designed for intelligent vehicle lighting systems. It features 12 channels, 4 groups, and 3 series high-voltage switches that can independently drive 12 ...

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.
