Getting Started with IoT
IoT Beginner Guide Getting Started with IoT From a blinking LED to a connected smart system — a beginner's guide for engineering students. The Internet of Things (IoT) is one of the most accessible areas for students to start building real projects. If you've seen our Smart Light project using ESP32, this guide shows you the bigger picture and how to level up. The 3 Layers of Every IoT System Layer 1 — Sensing Sensors collect real-world data: temperature, motion, light, humidity, gas levels. The physical world enters your system here. ï§ Layer 2 — Processing A microcontroller (Arduino, ESP32, Raspberry Pi) reads the sensor data and decides what action to take based on your code logic. Layer 3 — Actuation / Communication The system triggers a physical action (relay, motor, buzzer) or sends data to the cloud, a mobile app, or a dashboard. Beginner Kit Under ₹1,500 ESP32 Board ₹350–450 Better than Arduino for IoT — has built-in Wi-Fi and Bluetooth DHT11 / DHT22 ₹80 Measures temperature and humi…
