WeMos D1 Mini ESP8266 DevKit | Bitcoin Price Ticker | Tutorial & Project

Bitcoin Price Ticker is built with WeMos D1 Mini ESP8266 DevKit. It contains ESP12E Wi-Fi Module, which integrates an ESP8266EX Wi-Fi System-on-a-Chip (SoC). It supports IEEE 802.11 b/g/n wireless networking standards and operates on 2.4GHz frequency band. Bitcoin Price Ticker also uses a 0.66" I2C OLED Display Shield for displaying the current Bitcoin price.

WeMos D1 Mini ESP8266 DevKit will connect to your Wi-Fi network, to retrieve real-time Bitcoin price from the CoinDesk Bitcoin Price Index (BPI) API. The price is updated once in every minute. CoinDesk data is made available through a number of HTTP resources and is returned in JSON format.
