If you\u2019re like me, and you listen to music on a Yamaha R-N602 network receiver via Qobuz, you will \u00a0appreciate that the R-N602 can stream directly without needing a phone or tablet as an intermediary. Qobuz, with its detailed remastering, delivers the kind of sound quality that I prefer over other streaming services.<\/p>\n
However, there\u2019s a minor drawback: the R-N602\u2019s display doesn\u2019t show any track information\u2014just a generic \u201cQobuz\u201d label. I decided to fix this with a small, adaptable project using an Arduino R4 Wi-Fi and an LCD shield to display the track, artist, and album information in real-time.<\/p>\n
Project Overview<\/strong><\/p>\n The concept is straightforward: the Arduino connects to the same Wi-Fi as the R-N602, retrieves the currently playing track information from the receiver, and then displays it on a 2×16 LCD screen.<\/p>\n Here\u2019s how it works: Setting Up the Project<\/strong><\/p>\n Here\u2019s what you\u2019ll need: \u2022 To install some libraries needed by the project\u2014WiFiS3, ArduinoHttpClient, ArduinoJson and LiquidCrystal.<\/p>\n \u2022 Access to your WiFi credentials, which are saved in a separate arduino_secrets.h file. Here\u2019s how that file should look:<\/p>\n #define SECRET_SSID “Your Wifi SSID”
1. Interfacing with the R-N602: The Yamaha receiver serves a web page in JSON format, containing details about the current track. By connecting to this page, the Arduino can extract the artist, track title, and album name.
2. Displaying the Info: The artist and album are initially shown one per line on the LCD. Then, the track name appears across both lines. If the information is longer than the screen\u2019s width, it scrolls once to show the full text before switching to a truncated display.
3. Continuous Updates: The code loops to refresh the display periodically, keeping it in sync with the receiver\u2019s current playback status.<\/p>\n
