Triple beep
EasyBudget $4Python · gpiozero
An active buzzer on GPIO23 (wire it pi.GPIO23 >> Buzzer() >> pi.GND; it may draw up to 25 mA from the pin). Wait 0.5 s, then give exactly three beeps — 0.2 s on, 0.2 s off — and stay silent afterwards.
Tip: a for loop with on(), off() and sleep() does it; so does Buzzer.beep(0.2, 0.2, n=3), which beeps in the background.
