Please capitalize where necessary: to develop this small project, we will need a couple of resistors: an of 100 Ω (r1) , and another of 3.9k Ω (r2); a piezo buzzer as light as possible and operate between 3-5v (in my case i have chosen one of 1.5 grams and 30ma of consumption); a npn transistor bc548; and finally cable, tin, and welder; to understand that application has the transistor in our circuit in a simple way, visualize the following channel video of oliver nabani.
