Great for generating alarm sounds or 8-bit music, these piezo buzzers (speakers) are the perfect companion with your Arduino for an easy sound output.

Simply connect the buzzer between a digital pin (use PWM pins if you want to control the notes that are played) and ground (GND), and you have yourself a working simple 8-bit sound system.

These buzzers come in two varieties: a small black speaker the size of a coin, and a large white buzzer the size of a lip balm jar.
