This project is a simple, IoT-based real-time crypto price tracker built using the ESP32 microcontroller. It connects to your Wi-Fi network and retrieves live price data for coins like Bitcoin from the Binance public API.

The ESP32 parses this data and sends it to a UART-compatible display, updating the value every few seconds. It’s ideal for crypto enthusiasts, beginners in IoT, or anyone interested in learning how to work with APIs, JSON parsing, and serial communication.

You’ll learn:

  • How to connect ESP32 to the internet

  • Fetch data from the Binance REST API

  • Parse JSON in Arduino

  • Send real-time updates via UART to a display

This project can easily be extended to support multiple coins or display graphical information like trends or changes over time.
