  1. 01Place the Pico and four pushbuttons across the centre gap of a solderless breadboard.
  2. 02Connect one side of each button to ground and the other side to a Pico GPIO pin.
  3. 03Load CircuitPython with USB HID keyboard support and confirm the Pico appears as a keyboard.
  4. 04Map each button to a shortcut or short text macro and add a simple debounce delay.
  5. 05Plug the pad into a computer and try the four shortcuts in a text editor or browser.
  • This uses four breadboard-friendly tactile switches with small caps; no case or cutting is required.
  • The Pico sends normal USB keyboard reports, so no musical equipment or MIDI setup is needed.
