Virtual buzzer

Illustrative black piezo buzzer with two metal leads

OFF · Silent

Sound is optional and off by default. Enable it to hear a quiet browser-generated example tone while the buzzer is ON during a run. This is not a recording or prediction of a physical buzzer.

Teaching model: active-high buzzer output on GPIO 5. Real wiring needs board-specific drivers. App budgets: 10,000 steps/iterations, depth 32, 120 seconds total; waits 0.01–60 seconds. Exported files do not inherit these limits.

Execution output

Read-only code preview

Connect one Start and all supported blocks with valid values to preview or run.

Editor keyboard and screen reader access has not been verified. The surrounding instructions and controls are keyboard accessible. Practical alternatives: run the preloaded starter program, import/export workspace JSON, or inspect the read-only JavaScript, MicroPython, and C++ code preview.
