Tutorial 05: Connectivity
Go Online! Learn to connect your ESP32 to a WiFi network with robust disconnection handling. This tutorial sets the stage for network communication by displaying the connection status and IP address on an OLED screen. Wire up your setup, update the WiFi credentials, and watch your device go live!
What You Need: ESP32, 0.96" OLED (SSD1306), breadboard, jumper wires.
Key Features: Automatic reconnection, OLED status display.
Challenge (Optional): Integrate WiFiManager with a custom variable and enhance the OLED with connection feedback.
Tutorial 06: WebSocket
Stream Live Data! Take connectivity further by linking your ESP32 to a WebSocket server for real-time XRPL ledger updates. Display connection status and data on an OLED screen, log everything via Serial Monitor, and reset with a button press. Update your WiFi credentials and explore the live blockchain feed!
What You Need: ESP32, 0.96" OLED (SSD1306), tactile button, breadboard, jumper wires.
Key Features: WebSocket subscription, JSON parsing, reset functionality.
Challenge (Optional): Use WiFiManager for dynamic credentials, enhance display with ledger details, or visualize transaction counts.

Tutorial 07: Ledger Stream
Track the Ledger! Dive into monitoring XRPL ledger updates and transaction counts in real time. Use an RGB LED to indicate thresholds, display data on an OLED screen, and track the highest transaction count. Connect your components, upload the code, and see the ledger in action!
What You Need: ESP32, 0.96" OLED (SSD1306), RGB LED, tactile button, breadboard, jumper wires.
Key Features: Ledger streaming, high score tracking, RGB threshold indicators.
Challenge (Optional): Add a sound alert for high counts or create a graphical transaction count display.
Tutorial 08: Account Monitor
Watch Your Wallet! Monitor a specific XRPL account with WebSocket, displaying transactions on an OLED screen and triggering RGB LED and speaker alerts for events like payments or offers. Set your WiFi credentials and account address, then track your account’s activity live!
What You Need: ESP32, 0.96" OLED (SSD1306), RGB LED, tactile button, speaker/buzzer, breadboard, jumper wires.
Key Features: Account-specific monitoring, visual/audio alerts, high score tracking.
Challenge (Optional): Monitor multiple accounts or customize alerts for different transaction types.
