README
README.mdRFID-Spotify-Record-Player
Instead of vinyl records, RFID chips embedded in custom-made mini-records will trigger specific Spotify songs via a Raspberry Pi. The system mimics the action of placing a record on a turntable, offering both a visual spinning effect and the vast music library of Spotify.
Project Overview
The RFID Spotify Record Player allows users to:
- Play, pause, skip and control volume for Spotify tracks.
- Select songs or playlists through a physical interface using the RFID sensor.
- Output audio through a built-in speaker system.
- Watch a disk spin as if it were playing a vinyl record, adding to the aesthetic of a traditional record player.
Features
User Interface: Physical controls for playback and navigation.
Controller: Manages user inputs and communicates with Spotify.
Network Module: Connects to Wi-Fi to access the Spotify API.
Spinning Disk: A motorized disk spins to mimic the look of a record on a turntable.
Spotify Integration: Streams music directly from Spotify using the Spotify API.
Audio Output: Plays audio through connected speakers.

Questions
How big is the ECE411 Schematic PCB?
It measures 65 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ECE411 Schematic use?
33 parts, built around the LM386 and PCF8574T. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ECE411 Schematic KiCad files?
From the HT1929/RFID-Spotify-Record-Player repository on GitHub, at the commit this page was made from: the board is Schematic and Layout/ECE411_Schematic/ECE411_Schematic.kicad_pcb and its schematic Schematic and Layout/ECE411_Schematic/ECE411_Schematic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ECE411 Schematic design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
