![[150] Arduino Getting Started: Analog output and fading LED](https://i.ytimg.com/vi/lXvHp4AAIrM/mqdefault.jpg "[150] Arduino Getting Started: Analog output and fading LED
In this video, we delve into using Pulse Width Modulation (PWM) to control the brightness of an external LED connected to Digital Pin 11 of an Arduino Uno. This tutorial builds on our previous LED blink project, using the same circuit setup to demonstrate how PWM can simulate analog output for varied device control, including LEDs and motors. By varying the duty cycle of the PWM signal, we achieve a smooth fade-in and fade-out effect on the LED, showcasing the versatility and practical applications of PWM.
