ESP Price Tracker
An Arduino device that displays cryptocurrency prices and balances on a small LCD screen.
ESP Price Tracker is an embedded project that displays cryptocurrency prices and account balances through the Binance API on a 16x2 LCD keypad shield.
The device
The project combines an Arduino program with a small display, API requests, timestamp handling, and market-data parsing. It turns remote cryptocurrency data into a compact physical interface that can be read at a glance.
Supporting library
The tracker uses esp-binance-api, a C++ Arduino library developed to organize the Binance API requests. The repository separates market-data endpoints, HTTP requests, timestamp utilities, and display logic into focused files.
Why it matters
This project sits at the intersection of software and hardware: a web API, constrained embedded code, and a physical display working together as one small system.
