#Project objective: To test a passive buzzer to play an alarm sound at one second interval
#Hardware and connections used:
#Passive buzzer GND to Raspberry Pi Pico GND
#Passive buzzer + Pin to GPIO Pin 15
#If passive buzzer is used, import the Speakerclass
from picozero

from picozero import Speaker 
from time import sleep
#creating a speaker object
speaker = Speaker (15)
#Continuously beep at 1 sec interval while the board has power 
#Note: a passive buzzer can also be used to play different tones 
while True: 
speaker. On () 
sleep (1) 
speaker. Off () 
sleep (1)
