"🔥 Portable Bitcoin Price Tracker using ESP32 & ePaper Display
"

This project is a portable, low-power Bitcoin price monitoring device built using an ESP32 microcontroller and a 2.7-inch ePaper display. It fetches real-time Bitcoin (BTC-USD) prices from the internet and updates the display every 1 minute. Designed to be lightweight and battery-operated using a 3.7V Li-Po battery, this device is perfect for cryptocurrency enthusiasts who want to keep track of BTC prices on the go—without using a smartphone or computer.

The use of an ePaper display ensures minimal power consumption, as the screen only consumes energy during updates. The ESP32 connects to Wi-Fi and uses a free crypto API to fetch and display the latest price data, along with the current date. This project is perfect for demonstrating skills in IoT, wireless communication, low-power design, and real-time API integration.
