First of all We weld the collector of the transistor to the negative pin of the buzzer; It is important to look at the curvature of the transistor that can be seen in the previous scheme, and that will allow us to distinguish their pins at a glance.
Kwanza kabisa Sisi weld ushuru wa yaliwekwa kwenye mashine ili pin hasi ya buzzer na; Ni muhimu kuangalia curvature wa yaliwekwa kwenye mashine ya ambayo inaweza kuonekana katika Mpangano wa awali, na kwamba kuruhusu sisi kutofautisha zilizouzunguka tazamo la haraka.
