 **Note:** the value you choose for the ''BUZZER_PIN'' will define how you'll connect your buzzer to the quad. The current options allow you to choose between either the ''SWCLK'' or the ''SWDAT'' port for the signal connection. (this will become more clear once you're becoming familiar with the hardware and wiring explained below). **Note:** the value you choose for the ''BUZZER_PIN'' will define how you'll connect your buzzer to the quad.
