ESP32 Telegram Bot LED & Relay Control Kit — Build a Chat-Controlled IoT Project in 3 Hours

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

Imagine turning on a lamp in your room by sending a simple "ON" message through Telegram, and instantly receiving a confirmation "LED is now ON." This kit makes that real. You'll build a complete ESP32 project that listens to Telegram bot messages, toggles an LED or a relay module, and replies back to your phone — all using free cloud services. It's a perfect first step into home automation and IoT, no complex coding required, and you'll have a fully functional chat-controlled device by the end of the afternoon.

What You'll Build

By the end of this 2-3 hour build, you will have a working Telegram bot that controls real hardware over the internet. Use it to switch a lamp via the relay, signal status with bright LEDs, or even trigger a small motor. The system responds with Telegram text confirmations, giving you a taste of two-way IoT control that can later be expanded to monitor sensors or create custom commands. It's a complete project that works out of the box — you just connect to Wi-Fi, add your bot token, and you're live.

What You'll Learn

• Program an ESP32 to connect to Wi-Fi and Telegram API using Arduino IDE
• Wire a relay module and LEDs to control high-power devices safely with diodes and resistors
• Create and configure a Telegram bot using BotFather and obtain a personal chat ID
• Send and receive messages to control hardware with instant confirmations and error checks

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is ideal for CBSE Class 11-12 students diving into IoT and programming through hands-on informatics projects, ATL Tinkering Lab participants exploring automation challenges, and young makers (ages 10-15) who want to build their first internet-controlled gadget. B.Tech ECE/EEE students at institutions like IIT, NIT, VIT, or BITS will also find it useful for prototyping smart systems in hackathons like Smart India Hackathon.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
