Media meta serial transmitter for Arduino 16x2 LCD Char Displays.

Arduino Now Playing is a small project to provide source code to developers, enabling them to send "Now Playing" audio player metadata to an Arduino connected 16x2 character LCD display.
Included is also a sample client written in Go for periodically polling play status from an authorized Spotify account.
On the receiving end, an Arduino sketch listens via serial port, receives data, splits artist / track into two separate lines and displays via LiquidCrystal.h. Scrolling, if the length exceeds your usable display width.
Release Notes
- 2.26.2021 - Refactoring, cleanup, upgrade to Go 1.16, Spotify support.
- 4.26.2014 - Go port stable.
Spotify Configuration
- Create a Spotify developer account, app, retrieve OAuth client id, secret.
- Set environment variable values:
SPOTIFY_ID,SPOTIFY_SECRET. - On your Spotify developer app, ensure the callback URL is whitelisted:
http://localhost:8080/callback. - Run the Go spotify-client.
Roadmap
- Unit tests, probably.
- Additional support in Arduino sketch for very long titles.
- The sky's the limit, share your suggestions, please!
