TuneDeck: A Wi-Fi Enabled Physical Media Controller for Spotify

This project outlines the development of the TuneDeck, an IoT-based media control surface. The system architecture leverages the dual-core processing and native Wi-Fi capabilities of the ESP32 development board to manage secure HTTPS requests to the Spotify Web API. User input is captured via a KY-040 rotary encoder, which triggers state changes for volume scaling and playback toggling. The microcontroller parses JSON response payloads from the API to extract current track metadata, displaying the results locally on an SSD1306 OLED display. The TuneDeck highlights key mechatronics principles by successfully integrating physical sensor inputs, local microprocessor logic, and wireless network communication into a cohesive, standalone desktop appliance.
