Pou devlope ti pwojè sa a, nou pral bezwen yon koup résistances: yon moun 100Ω (R1), ak yon lòt nan 3.9SOUFRIΩ (R2); yon sonnèt piézo-électriques tankou limyè ke nou kapab ak opere ant 3-5V (nan ka m, mwen te chwazi yonn nan 1.5 gram yo ak 30mA de konsomasyon); yon NPN tranzistò BC548; ak a la fen kab, Eten, ak soudeur; pou w konprann aplikasyon sa ki tranzistò a nan chan de kous nou nan yon fason byen senp, visualiser swiv chanèl videyo de Oliver Nabani.

To develop this small project, we will need a couple of resistors: an of 100Ω (R1), and another of 3.9KΩ (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.
