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 ...

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.

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 ...

LED brightness control is achieved with PWM dimming from an analog or PWM input signal. Unique PWM circuitry allows true constant color with a high dimming range. The dimming frequency is programmed ...

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 LDS8711 is fixed-frequency current mode boost converter featuring Smart OneWire™ interface and PWM LED brightness control modes that provide constant current or constant color temperature ...
