Workshop 04: Cardano Ticker

This workshop builds a complete Cardano ticker: a multi-screen TFT display that rotates between your ADA balance, your token holdings with prices from MinSwap, your NFT collections with floor prices from Cexplorer, and a status screen - plus a stock-market-style scrolling ticker along the bottom.

The example uses mainnet data (the original CardanoThings wallet). API endpoints used here are intended for educational purposes; a production ticker would need official paid APIs or a self-hosted source.

Source code: github.com/CardanoThings/Workshops/tree/main/Workshop-04

Steps​

  1. Gathering Data - APIs and endpoints used: Koios for stake balance, MinSwap portfolio API for token prices, Cexplorer for NFT collection floor prices. Includes a note on TapTools and Charli3 for production use.
  2. Building the Ticker - Walk through a multi-file Arduino project: WiFi manager, data fetcher, four data screens (wallet, tokens, NFTs, status) and the scrolling ticker.

What you'll need​

  • Cheap Yellow Display (CYD) or compatible ESP32 + TFT setup from Workshop 02.
  • A free Cexplorer.io API key.
  • Libraries already installed from earlier workshops: TFT_eSPI, ArduinoJson, WiFi, HTTPClient.
