What's inside
Everything you need to go from zero to IoT
A complete, step-by-step guide that builds on itself. Each section ends with working code you can flash to your board immediately.
ESP32 setup & first blink
Install the toolchain, wire your first LED, and understand the development workflow from IDE to board.
WiFi & web server
Connect to your network and serve a live dashboard from the ESP32 — accessible from any device on your LAN.
Sensor data collection
Read temperature, humidity, and light sensors. Format the data as JSON and display it in real time.
MQTT messaging
Publish sensor readings to an MQTT broker and subscribe from other devices. The backbone of any IoT system.
Live dashboard UI
Build a clean, responsive web dashboard with charts that auto-update as new readings come in.
Security & OTA updates
Secure your endpoints, add API authentication, and push firmware updates over-the-air without touching the board.
