Step 2: Schematic Diagram

connect - to ground pin and + to gpio pin 16

Step 3: Source Code

# Active Buzzer micro python by Cryp7o

import utime

from machine import Pin

# Create a Pin object named "buzzer" connected to GPIO pin 16 as an output

buzzer = Pin(16, Pin.OUT)

while True:

# Turn the buzzer on

buzzer.high()

# Pause the program execution for 1 second

utime.sleep(1)

# Turn the buzzer off

buzzer.low()
