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 ...

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 ...

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 ...

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 ...

Hi there, and welcome to Part 3 of this soon-to-be-heralded mega-mini-series. In Part 1, we discussed the first vacuum tube diodes, moved on to their solid-state (semiconductor) descendants, and then ...

White LEDs (WLED) are increasingly becoming the light source of choice for backlighting applications due to their attractiveness in power efficiency and form factor. Display solutions in portable ...

Most engineers are quite familiar with typical low-power-indicator LEDs, whether they be surface-mount or the classical through-hole packages. All that's needed to use them is a voltage source and a ...

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 ...

MILPITAS, Calif., May 08, 2023 (GLOBE NEWSWIRE) — Lumissil Microsystems, a division of Integrated Silicon Solution, Inc. (ISSI), announces the release of its latest 48-channel LED driver with a ...

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.
