In a two computer setup, the computer playing my music doesn't always have a keyboard connected. Using a Leonardo and a touchscreen LCD display, play back and volume controls are always available.

EXPANDED TECHNICAL DETAILS

Tactile Digital Audio Interface

This project transforms an Arduino into a dedicated hardware remote for controlling music and video playback on any PC or Mac.

  • HID (Human Interface Device) Emulation: Uses an Arduino Micro or Pro Micro (ATmega32U4). The firmware identifies itself to the computer as a standard USB Keyboard/Media Key module, allowing it to send "Play/Pause," "Next Track," and "Volume" commands natively.
  • Rotary Encoder Precision: Features a high-quality rotary encoder for volume control. The Arduino manages the high-speed interrupts from the encoder to provide smooth, click-accurate volume increments without lag.

Customization

  • Multi-App Macro Matrix: Includes a "Mode Switch" button; users can toggle between "Spotify Mode" and "YouTube Mode," with the Arduino sending different key combinations (e.g., Spacebar vs. Media_Play) for each app.
