Скачать или смотреть Pulse Width Modulation (PWM) Explained: Control LEDs & Motors with Duty Cycle & Frequency

In this video, we explore the fundamentals of Pulse Width Modulation (PWM) and how it allows us to control devices like LEDs and motors. You’ll learn how PWM works by switching digital signals ON and OFF quickly, simulating analog behavior. We dive into the two key components of PWM: duty cycle and frequency.

Duty cycle determines how long the signal stays ON during each cycle, affecting brightness or motor speed.
Frequency measures how many times the signal repeats per second, controlling how smooth or flickering the output appears.
Whether you’re new to electronics or looking to enhance your understanding of digital signal control, this video will give you the essential knowledge you need to get started with PWM. Don’t forget to subscribe for more tutorials!
