Light emitting diodes (LEDs) deliver emitted light in response to current being made to flow through them, but then you already knew that, right?? If we define that the light output of an LED is ...

Adaptive brightness control has become a common feature in modern smartphones, HDTVs, PDAs, tablets, and computer screens. The goal of this feature is to conserve power as well as to make the display ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

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 ...

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 ...

This project uses an ultrasonic sensor and an Arduino to measure distance and dynamically control the brightness of an LED. As an object moves closer to the sensor, the LED becomes brighter. As the ...

A custom VHDL peripheral for the DE10-Lite FPGA board that extends basic LED control with PWM brightness modulation, gamma correction, and configurable flash modes. Built as a peripheral for the SCOMP ...

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.
