Txoj haujlwm no hais txog kev sib txuas lus ob tus tib neeg nrog cov kab hluav taws xob yooj yim. Nov yog kuv tshooj lus qhia txog kev siv hluav taws xob hauv hluav taws xob. Kuv xav ua video txog nws.

Nqe lus piav qhia ntawm no yog qhov yooj yim tab sis muaj txiaj ntsig intercom Circuit Court uas yog tsim los ntawm transistors. Qhov Circuit Court yog raws li peb theem RC txuas ua ke txuas nrog. Thaum lub laub khawm S2 raug nias, lub tshuab hluav taws xob Circuit Court wiredaround T1 & T2 dhau los ua qhov zoo tshaj plaws multivibrator thiab pib tsim cov cim qhia. Cov suab nrov nrov no yuav nthuav los ntawm transistor T3 kom tsav tus hais lus. Thaum lub laub khawm S1 raug tso tawm lub Circuit Court yuav ua raws li lub suab nrov zoo ib yam thiab koj tuaj yeem tham nrog lwm sab los ntawm nws. Txhawm rau tsim ob txoj hauv kev intercom, ua ob daim qauv zoo ib yam ntawm cov kab lus muab hauv qab no thiab txuas nws raws li daim duab qhia kev sib txuas. Qhov sawv ntsug los ntawm kev siv tam sim no ntawm Circuit no yog ib puag ncig 20mA.

Sau ntawv

Sib sau ua ke Circuit kom zoo PCB. Use 9V PP3 roj teeb rau lub zog hluav taws xob. Qhov Mic M1 tuaj yeem yog lub xov tooj cua txias. Kev siv nias rau ON hom laub khawm hloov rau S2. Ua tus swb swb rau hloov S1. S1 tuaj yeem siv tau txhawm rau txuas lub zog. BEL 187 sib npaug 2N2222, 2N4401, BC 548 Koj tuaj yeem hloov BC548 nrog BC546, BC547, BC549, BC550
