Lecture
PWM: Pulse Width Modulation
Description
This lecture covers the principles of Pulse Width Modulation (PWM) used in LED displays and signs. It explains how to vary the intensity of LEDs, program PWM signals with microcontrollers, and handle multiple PWM signals simultaneously. The frequency range of PWM applications, programming techniques, and the use of PWM sequences are also discussed, along with the implementation of PWM using digital-to-analog converters and logic circuits.
