3.8 2.2 Fading LED
In the previous project, we controlled the LED by turning it on and off using digital output. In this project, we will
create a breathing effect on the LED by utilizing Pulse Width Modulation (PWM). PWM is a technique that allows us
to control the brightness of an LED or the speed of a motor by varying the duty cycle of a square wave signal.
With PWM, instead of simply turning the LED on or off, we will be adjusting the amount of time the LED is on versus
the amount of time it is off within each cycle. By rapidly switching the LED on and off at varying intervals, we can
create the illusion of the LED gradually brightening and dimming, simulating a breathing effect.
By using the PWM capabilities of the ESP32 WROOM 32E, we can achieve smooth and precise control over the
LED’s brightness. This breathing effect adds a dynamic and visually appealing element to your projects, creating an
eye-catching display or ambiance.
