A physical Bitcoin Ticker. For use with Arduino ESP32 board and I2C OLED display.
FIT ONLY FOR PERSONAL USE
If you would like to utilize it commercially, please get in contact with me. I'm open to reaching a consensus.
ESP32 boards can run the Arduino code for Bitcoin Ticker. This ticker shows the price of Bitcoin relative to the US dollar and indicates a rise or fall in the virtual currency. The CoinMarketCap API provides the price information.
- 0.96 Inch OLED Module 12864 128x64 Yellow Blue SSD1306 Driver I2C IIC Serial Self-Luminous Display Board
- ESP32 ESP-32S Development Board
Connect your ESP32 board to your computer and open bitcoinTicker.ino with the Arduino IDE.
In Tools > Board select DOIT ESP32 DEVKIT V1.
Select the correct port that your ESP32 is plugged into via Tools > Port. If your board isn't showing up, you might need to install some drivers. A Google Search for ESP32 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)
- WiFi (For ESP32 onboard WiFi)
- Wire
- HTTPClient (To make requests to CoinMarketCap)
- NTPClinet (Used to get the time for "Last Updated")
- WiFiUdp (Used to get the time for "Last Updated")
- 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.
I am using the MELIFE ESP32 ESP-32S Development Board.
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.
