ESP32 LED Control: Turn On/Off the Inbuilt LED|Beginner Tutorial_1

In this video, you’ll learn how to enable and disable the built-in LED on your ESP32 Board using simple code. This is a perfect beginner project to get started with ESP32 and understand how digital output works.

What you'll learn:

How to control the onboard LED (usually on GPIO2 Pin)

Writing a basic sketch using digitalWrite()

Uploading the code to your Arduino board


1.Components Used:

1.1.ESP32 DEVKITE V1_1NOS

AMAZON Link: https://amzn.in/d/iZQn0gj

1.2.USB cable
AMAZON Link: https://amzn.in/d/9Pe22q8

Step 1: Install the Driode App

Go to Play Store

Search and install Driode or ArduinoDroid

Open the app


Step 2: Connect ESP32 to Your Phone

Plug your ESP32 into the USB cable

Connect that to your phone using an OTG adapter

Give USB permission when prompted


Step 3: Install Board Support (First Time Only)

In the app, go to Boards or Settings

Search and install ESP32 support

May take a few minutes the first time


Step 4: Write or Paste Code

Use this code to blink the built-in LED (usually GPIO 2):

#define LED_BUILTIN 2

void setup() {
pinMode(LED_BUILTIN, OUTPUT);
}

void loop() {
digitalWrite(LED_BUILTIN, HIGH); // Turn on
delay(1000);
digitalWrite(LED_BUILTIN, LOW); // Turn off
delay(1000);
}

Step 5: Compile and Upload

Click the "Verify/Compile" button

Then tap Upload

If prompted, press the BOOT button on ESP32 until upload starts


Step 6: Watch It Work!

Your ESP32’s onboard LED will now blink every second!

Disable inbuilt led

A) Upload a Code that Keeps LED OFF

Here’s a simple code that disables the built-in LED (GPIO 2) and keeps it OFF:

#define LED_BUILTIN 2

void setup() {
pinMode(LED_BUILTIN, OUTPUT);
digitalWrite(LED_BUILTIN, LOW); // Keep LED OFF
}

void loop() {
// Nothing here, LED stays OFF
}


How to Upload (Same Steps in Driode App):

1. Open the Driode App


2. Connect your ESP32 via OTG


3. Paste the code above


4. Click Compile, then Upload


5. Press the BOOT button on the ESP32 when asked



Done! The LED on your ESP32 will now remain OFF.
