Build a WiFi Relay Switch with ESP8266 — Control Appliances from Your Browser

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

With this kit, you’ll assemble a WiFi-connected relay that lets you turn a lamp, fan, or any appliance on and off from a web browser on your phone or laptop. The intuitive interface updates instantly, showing whether the appliance is active — no app downloads, no cloud dependency, just your local network. It’s a real-world introduction to IoT without the complexity of external platforms.

What You'll Build

You’ll wire an ESP8266 NodeMCU to a 5V relay module, two status LEDs, and protection diodes on a breadboard. Then you’ll flash the microcontroller with ready-to-customize code that hosts a simple web page. When your device connects to the same WiFi network, opening a browser URL brings up buttons to toggle the relay — and an LED that mirrors the real state. The complete circuit is stable enough to leave running as a permanent home automation gadget.

What You'll Learn

• Programming an ESP8266 using Arduino IDE and its WiFi libraries
• Wiring a relay module to safely switch high-voltage AC appliances
• Creating a web server on a microcontroller that serves real-time HTML
• Using flyback diodes and current-limiting resistors to protect components
