Software Setup
To follow along, install the following libraries via the Arduino Library Manager:
Use Example4_QwiicTwist.ino from the SparkFun MY1690 MP3 Decoder Library examples. It enables the Qwiic Twist to:
- Rotate to change track number
- Press to play the selected track
- Display info via serial monitor
How It Works:
- The Audio Player Breakout receives serial messages from the RedBoard Qwiic.
- The Qwiic Twist allows you to navigate through tracks by rotating and play one by pressing.
- The selected audio file is played through the MY1690 and sent to the mono amp and speaker.
Serial Feedback: The sketch prints useful debug messages to the Serial Monitor, including the number of tracks on your SD card and the currently selected track.
Tips:
- Make sure your microSD card is formatted correctly and contains MP3/WAV files.
- Use a single-cell LiPo if you'd like to run this portable.
- You can customize the playback behavior by editing the example sketch.
