Say it to PAL
“Beep when something needs my attention.”
The code PAL writes
p.write('modulino-buzzer', 'tone', { frequency: 1000, duration_ms: 200 });“Make it chime like a doorbell.”
The code PAL writes
p.write('modulino-buzzer', 'tone', { frequency: 523, duration_ms: 300 });
await p.sleep(350);
p.write('modulino-buzzer', 'tone', { frequency: 392, duration_ms: 500 });When to pick it
Usable range 200-3000 Hz.
Good to know
- Below 100 Hz: barely audible. Above 5000 Hz: piercing. Sweet spot: 440-1000 Hz.
- New sound ALWAYS stops the previous one mid-play. Cannot play chords or layer sounds.
