Control LED with ESP32 & Blynk App | IoT Beginner Project
Difficulty: EasyWelcome to IoT Craft Hub! In this video, we'll build a Smart LED Control system using the ESP32 microcontroller and the Blynk app. This project is perfect for beginners who want to explore IoT and smart home automation.
In this tutorial, you'll learn:
✅ How to set up the ESP32 to control an LED
✅ How to configure the Blynk app for remote control
✅ How to write and upload Arduino code for ESP32
💡 Components used:
ESP32 board
LED
330-ohm resistor
Breadboard and jumper wires
📲 Blynk App Setup:
We’ll configure a virtual button in the Blynk app to control the LED remotely.
