=========

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

----

1. Create a Spotify developer account, app, retrieve OAuth client id, secret.

2. Set environment variable values: `SPOTIFY_ID`, `SPOTIFY_SECRET`.

3. On your Spotify developer app, ensure the callback URL is whitelisted: `http://localhost:8080/callback`.

4. 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!
