Introduction
In this project, we’ll build a real-time cryptocurrency tracker using an ESP32 microcontroller and a Nextion TFT touchscreen display. The dashboard connects to the internet, fetches live prices from Binance, and shows:
Current price
24-hour percentage change
High/low values
A real-time chart that auto-scales
You can also interact with the display to:
Switch coins (BTC, ETH, DOGE, etc.)
Change timeframe (1m, 15m, 1h, 24h, 7d)
Watch alerts trigger for support/resistance
All powered by the ESP32 — no external PC or cloud server needed.
