Preparations

Install Arduino IDE
Install Arduino libraries

 $> cd Arduino/libraries/
 $> git clone https://github.com/foogadgets/spotify-api-arduino.git
 $> git clone https://github.com/foogadgets/Sony_SLink.git
 $> git clone https://github.com/foogadgets/MusicAlbumTOC.git

Tools -> Manage Libraries etc.
Search for ArduinoJson and install the package.
Search for arduinoWebSockets and install the package.

Install the slinktool code in your workspace,

$> cd <your workspace>
$> git clone https://github.com/foogadgets/slinktool.git
$> cd slinktool/

Install node.js environment for the slink project

 $> cd html-generator/
 $> npm install
 $> npm run build
 $> ./gen_compact_index_file.sh
 $> cd ..

Note that the following commands need to be run after any change in the JS- or HTML-files.

 $> npm run build
 $> ./gen_compact_index_file.sh

Start Arduino IDE and open slinktool.ino

Go to menu Arduino -> Preferences and paste following,
Additional Boards Manager URLs:
http://arduino.esp8266.com/stable/package_esp8266com_index.json Press OK

Go to Tools -> Board -> Boards Manager…
Search for esp and install esp8266

Go to Tools -> Board -> ESP8266 Boards -> LOLIN(WEMOS) D1 R2 & mini

(på OS X behöver man installera egen python3. Det gjorde jag med hjälp av Homebrew. Homebrew kräver dessutom Java JDK samt att jag behövde justera sökvägen till python3 i espressif i filen platform.txt)

Update the wifi credentials in Credentials.h

Build and flash to LOLIN(WEMOS) D1.

Build and upload sketch to your LOLIN.

Using SLink Tool

Browse to http://slinktool.local/
Main page,

To be able to automatically populate album and track data and to automatically record from Spotify you need to be a Spotify Premium user.
