Embedded Cryptocurrency Price Tracker
This project utilises an ESP32 and an Adafruit SSD1306 OLED Screen to track and display cryptocurrency prices.
How it Works
The program uses the in-built wifi module in the ESP32 to send a GET request to a custom API. A sample python program that creates a flask web server hosted on Heroku was made to simplify requests from the ESP32, allowing API changes to be made only on the server-side. Once the the request is made the price on screen is updated and the animation is changed depending on whether the price has increased or decreased.
