Buzzer Music

Play a simple tune using an Arduino and a Buzzer.   Component List:

• 1 x Arduino Uno R3
• 1 x Female to Male Jumper Wire
• 1 x Passive Buzzer

Wiring Guide:

1. Connect one leg of the buzzer to digital pin 9 on the Arduino.
2. Connect the other leg of the buzzer to the ground (GND) on the Arduino using a jumper wire
