GitHub link for Project files and code: https://github.com/Sanketjain0205/Internet-Of-Things-Blynk-projects

This video is a complete beginner-friendly IoT tutorial using NodeMCU ESP8266 and Blynk IoT.

In this step-by-step guide, you will build your first real Internet of Things project where you control an LED from your mobile phone using Wi-Fi.

This tutorial is perfect for students and beginners who already know Arduino and are entering the world of ESP8266 and IoT for the first time.

🔧 What you will learn in this video:
• What is IoT (Internet of Things)
• How ESP8266 connects to Wi-Fi
• CH340 driver installation (Windows)
• Arduino IDE setup for ESP8266
• Installing ESP8266 boards in Arduino IDE
• Blynk IoT account setup (cloud.blynk.io)
• Creating template and device in Blynk
• Understanding Auth Token, Template ID, Template Name
• Difference between Physical Pins and Virtual Pins
• Creating a dashboard in Blynk mobile app
• Controlling LED using Virtual Pin V0
• Serial Monitor debugging (Wi-Fi, IP address)
• Fixing common errors:
• Board not detected
• Auth token invalid
• Device offline
• Safety tips for ESP8266 beginners

🧪 Project Used:
• NodeMCU ESP8266
• External LED on D4
• USB power only
• Blynk IoT (New Version)

📱 Blynk App:
• Android supported
• iOS supported

⚠️ Important Notes:
• ESP8266 works only on 2.4 GHz Wi-Fi
• Always remove USB before wiring
• Never short 3.3V to GND

🎯 Student Task:

Make your LED work from the mobile app.
