ESP32 LED Dimmer

The ESP32 LED Dimmer project demonstrates how to control the brightness of an LED using pulse width modulation (PWM). PWM allows for smooth control of LED brightness by rapidly switching the LED on and off at varying intensities.

Components Needed

Circuit Setup

Connecting LED to ESP32:

Connect the anode (longer leg) of the LED to GPIO pin 2 on the ESP32.

Connect the cathode (shorter leg) of the LED to ground through a current-limiting resistor (if necessary).

Instructions

setup:

Define the GPIO pin

operation:

In the

Use two for loops to control the brightness of the LED:

First loop increases the brightness gradually from off to full brightness using

Second loop decreases the brightness gradually from full brightness back to off using

Adjust the delay between each brightness level (

considerations:

PWM Control: ESP32 supports PWM on certain GPIO pins, which is essential for controlling LED brightness.

Current Limiting: Ensure the LED current is within safe operating limits to avoid damage.

Power Supply: Ensure the ESP32 has adequate power supply to drive the LED.
