ESP32 LED

This project focuses on controlling an LED using an ESP32 microcontroller. LEDs are fundamental components used in various electronics projects for visual indication and status signaling.

Components Needed

ESP32 Microcontroller
LED
Resistor (if needed for current limiting)
Jumper Wires
Breadboard (optional)

Circuit Setup

1.Connecting the LED to ESP32:

Connect the positive (anode) leg of the LED to GPIO pin 2 (or any other GPIO pin of your choice).

Connect the negative (cathode) leg of the LED to ground (GND).

Instructions

1.setup:

Initialize GPIO pin 2 as an output using pinMode() in the setup() function. This prepares the GPIO pin to control the LED.

2.operation:

In the loop() function:

Set the digital output of GPIO pin 2 to HIGH (digitalWrite(ledPin, HIGH)) to turn on the LED.
Use delay(1000) to keep the LED on for 1 second.
After 1 second, the LED turns off automatically due to the next iteration of the loop, where digitalWrite(ledPin, HIGH) is not executed.

3.considerations:

Current Limiting: Ensure the LED current does not exceed its maximum rating. Optionally, use a current-limiting resistor in series with the LED if needed.

Power Supply: ESP32 can power LEDs directly from its GPIO pins, but ensure overall current draw does not exceed ESP32's capabilities.
