A developer repurposed an old landline telephone into a Spotify controller by reverse-engineering its keypad matrix and wiring it to an ESP32 microcontroller. The project enables dialing numbers to trigger specific music playback commands, blending retro hardware with modern software integration. While not groundbreaking, it demonstrates creative hardware hacking and practical IoT application.
Background
DIY hardware projects often involve repurposing outdated devices with modern microcontrollers like ESP32 for new functionalities. Spotify’s API allows external hardware to control playback, enabling creative integrations.
