Image result for work with piezo buzzer in arduino
It's painfully easy to set up a simple piezo speaker circuit with an Arduino.
Place the piezo buzzer into the breadboard, so that the two leads are on two separate rows.
Using jumper wires, connect the positive lead to Arduino digital pin 8. ...
Connect the other lead to the 100 ohm resistor, and then to ground.
How it works? It's simple, tone(buzzer, 1000) sends a 1KHz sound signal to pin 9, delay(1000) pause the program for one second and noTone(buzzer) stops the signal sound. The loop() routine will make this run again and again making a short beeping sound.
Does a piezo buzzer need a resistor?
Don't we need a resistor to limit the current through the buzzer? No, if you are using a small 5V Piezo. As it derives or uses very small amount of current so can be used without a resistor in series.
A buzzer or beeper is an audio signalling device, which may be mechanical, electromechanical, or piezoelectric (piezo for short). Typical uses of buzzers and beepers include alarm devices, timers, and confirmation of user input such as a mouse click or keystroke.

What is a buzzer symbol?
A buzzer converts electricity into sound when current flows through it. It is drawn as half a circle with two short lines extending down.
How much voltage does a buzzer need?
In contrast to the magnetic buzzer, the piezo buzzer is a voltage-driven device; the operating voltage is usually higher and may be between 12V and 220V, while the current is less than 20mA.
How do you connect a battery to a buzzer?
Attach one wire to the positive terminal of the battery holder and the other wire to the negative terminal. Wrap electrical tape around the two bare wires on the battery holder. This will ensure that they do not touch each other and create a short circuit. Attach the other ends of the wires to the buzzer.
How do you check if a buzzer is working?
Typically, the buzzer test is done by controlling the buzzer to sound a continuous buzzing sound while a test engineer listens to the buzzer with ears to determine if the buzzer is in working condition.
