PWMdim
PWMdim refers to a method of controlling the brightness of light-emitting diodes (LEDs) using Pulse Width Modulation (PWM). PWM is a technique for generating an analog output value from a digital system by chopping a digital signal. In the context of LEDs, a PWM signal rapidly switches the LED on and off. The perceived brightness of the LED is determined by the ratio of the "on" time to the total period of the signal, known as the duty cycle. A higher duty cycle, meaning the LED is on for a longer portion of the cycle, results in a brighter output. Conversely, a lower duty cycle makes the LED appear dimmer.
This method is widely used in LED lighting systems, motor speed control, and other applications where a
