#Project objective: To test a passive buzzer to play an alarm sound at one second interval
#
#Hardware and connections used:
#   Passive buzzer GND to Rasberry Pi Pico GND
#   Passive buzzer + Pin to GPIO Pin 15
#
#Programmer: Adrian Josele G. Quional

#if passive buzzer is used, import the Speaker class from picozero
from picozero import Speaker

#creating a speaker object
speaker = Speaker(15)

#continously 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)
