I was searching for a LED driver that can also act as dimmer for ... The frequency of PWM dimming ranges from 100Hz to more than 20 kHz. The dimming effect is achieved using PWM provided by an Arduino ...

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 ...

Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller ... BCM does the same thing as PWM, it turns the LED on and off very rapidly so that your ...

He used four powerful soft-white LEDs, mounting them ... included is own controller. An Arduino drives the switch-mode power supply, offering dimming thanks to PWM, and the ability to ...

High-brightness LEDs (HBLEDs ... usually have a pulsewidth- modulator (PWM) input that enables a pulse train of varying duty cycle to provide the dimming function. One problem, however, in ...
