 **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.

 //Note: for about $6 you'll have enough to build 10 buzzers + a lot of spare "stock" components. I intentionally gave advice to purchase larger quantity than needed as the cost between 1 item and 10-100 is often a few cents. It doesn't make sense to order a single component from ebay. Remember to sort results by "Price + Postage: lowest first"!!// //Note: for about $6 you'll have enough to build 10 buzzers + a lot of spare "stock" components.
