Bitcoin Ticker is Arduino code for ESP8266 boards. This ticker displays the price of Bitcoin/USD and idicates whether the crypto currency went up or down. The price data comes from the CoinMarketCap API.
(FYI - there are affliliate links here to hardware you might need.)
- 0.96 Inch OLED Module 128x64 SSD1306
- ESP8266 ESP-12 ESP-12F NodeMcu Mini D1 Module
- Breadboard Kit - I used a half sized breadboard.
- Jumper Wires - I've linked my favorite ones.
Connect your ESP8266 board to your computer and open bitcoinTicker-esp8266.ino with the Arduino IDE.
In Tools > Board > ESP8266 Boards select Generic ESP8266 Module.
Select the correct port that your ESP8266 is plugged into via Tools > Port. If your board isn't showing up, you might need to install some drivers. A Google Search for ESP8266 Drivers should give you what you need.
Hit the Verify button. Install any necessary libraries via Tools > Manage Libraries. Below is the list of libraries I used in this project. You should be able to find them pretty quick by typing these into the search bar. All libraries are found in the Arduino Library Manger(Tools > Manage Libraries.) No special installation is needed outside of their library.
Libraries Used:
- Adafruit_SSD1306 (For the OLED Display)
- ESP8266WiFi (For ESP8266 onboard WiFi)
- Wire
- ESP8266HTTPClient (To make requests to CoinMarketCap)
- ArduinoJson (Used to process JSON data retreived from CoinMarketCap)
Once everything is verified successfully, hit the Upload button. If your OLED is wired up correctly, you should see the screen displaying that it's connecting to your network, then it will show the ticker.
Plug Micro-USB into the Arduino and everything should boot up successfully in less than 10 seconds.
Whatever you need; questions answered, requests, bugs; make an Issue. I'll get to them as soon as I can.
