ESP32 | LED Interfacing | Wokwi Simulator | #iot

Interfacing an LED with an ESP32 microcontroller is a basic yet fundamental task in hardware programming. Below, I'll outline a simple example using the Arduino IDE, assuming you have the necessary setup with an ESP32 development board and an LED connected to one of its GPIO pins.

Hardware Setup:
Connect the cathode (short leg) of the LED to a current-limiting resistor (usually between 220-1000 ohms).
Connect the other end of the resistor to one of the GPIO pins on the ESP32.
Connect the anode (long leg) of the LED to the 3.3V pin on the ESP32.
