Qhov no yuav piav qhia qhov yooj yim Circuit Court rau kev tso cai rau 9 v. Ib yam dab tsi zoo sib xws tau thov hauv nqe lus nug ntawm cov rooj sab laj. Kuv vam tias qhov no muaj txiaj ntsig raws li tus qauv, lossis hauv kev txhawb siab lub tswv yim yuav siv qhov teeb tsa no li cas.

Nov yog cov lus nug ntawm cov khoom kuv siv: Q1: feem ntau ntawm SS (teeb liab me me) NPN transistor yuav ua ntawm no. C1: 100-330 uaF electrolytic polarized capacitorD1: Kuv tau siv Rainbow flashing LED (yog li daim phiaj no yuav nyem), yog tias siv LED ib txwm siv, nws yuav tsis nyem. R1: 10k resistor (carbon, 1/4 w yog qhov zoo). Rau R1, Kuv siv 1 K resistor hauv koob nrog 10K potentiometer, rau kev hloov kho lub hom phiaj. PB: ib txwm qhib (N/O) laub khawm hloovMisc: hlau, pc board (lossis pawg thawj coj saib lub rooj), 9 v roj teeb snap (thiab roj teeb), xav tau cov ntaub ntawv tsim

Nov yog cov kauj ruam kom ua tiav txoj haujlwm no: Txij li cov txheej txheem yog qhov ncaj ncaj, Kuv tsuas yog siv txhua yam raws li kuv tau kos nws, tshwj tsis yog PB, LED, thiab lauj kaub. PB hloov, LED thiab lub lauj kaub., Kuv tau txuas rau me ntsis xaim ntxiv yog li kuv tuaj yeem txhim kho lawv ntawm qhov thiab lub qhov uas kuv tau txiav rau hauv lub thawv. Kuv lub thawv yog lub thawv me me zoo li lub plua plav npog rau cov kab xev thaub qab uas tau muab pov tseg qhov twg kuv ua haujlwm. Lawv ua kom yooj yim heev los ua haujlwm nrog rooj plaub, tab sis tseem khov kho. Saib ntawm Schematic, thiab tom qab tau txais kuv lub transistor (thiab sab laj tus pin tawm ntawm daim ntawv), Kuv pom tias kuv tus transistor tau teeb tsa (saib hauv qab, nrog lub tiaj tiaj tiaj) Emitter, hauv paus, tus sau (E, B, C) ntawm schematic). Siv cov txheej txheem cua sov ua cua sov, kuv tau siv lub tshuab hluav taws xob ntawm ib qho kawg ntawm PC board. Yog tias koj xav tias tsis yooj yim txog qhov no, peb tus pin transistor qhov muaj nyob ntawm qee qhov kev txhawb nqa (qhov no ua rau hloov pauv tau yooj yim ntawm transistor yog xav tau yam tsis muaj soldering). Kuv tau khiav ib lub xov hlau los ntawm lub tshuab hluav taws xob (E) mus rau qhov chaw ntawm lwm qhov kawg ntawm kuv lub PC pawg thawj coj uas yuav txuas rau hauv av ntawm Lub Hwj Chim. Txog qhov no, tom qab ntawd kuv tau siv tus lej tsis zoo (cim nrog tus cim) ntawm C1. Tus pin zoo (ib txwm tsis cim) tau muab nkag rau hauv lub rooj tsavxwm, thiab tom qab ntawd kuv tau siv hauv R1. R1 tau khiav los ntawm lub capacitor mus rau (B) ase ntawm transistor. Ntawm kev sib koom ua ke ntawm R1 thiab C1, Kuv tau xaim ib lub xov hlau uas thaum kawg yuav raug muab txuas rau ib tus pin ntawm lub laub khawm (PB) hloov. Lwm sab ntawm qhov hloov pauv (lwm tus pin) tom qab ntawd tau muab muag rau + cov tswv yim los ntawm lub roj teeb THIAB mus rau qhov zoo ntawm LED. Lwm tus pin ntawm LED yog tom qab ntawd txuas rau lwm lub xaim uas tom qab ntawd muab txuas rau (C) tus lej hluav taws xob tus pin ntawm lub transistor.

Thawj zaug kuv rho nws tawm, nws tsis ua haujlwm. Kuv sim ntau yam….tab sis tsis muaj dab tsi yog teeb pom kev zoo LED. Tom qab ntawd kuv txiav txim siab ntsuas qhov ntsuas hluav taws xob hla LED thiab zoo muaj koj qhov teeb meem nyob ntawd!, Tsis muaj hluav taws xob hla LED. Taug qab rov qab los ntawm cov pob qij txha txuas, Kuv pom ib qho chaw uas muaj ze li ntawm cov plaub hau tawg hauv cov laug. Txhim kho qhov sib txawv ntawd kho qhov teeb meem.

Ntawm no kuv mus me ntsis pheej yig thiab pom "tsis-plam nto qauv los hloov rau kuv cov ntaub ntawv (zoo, luam tawm ntawm nws ntawm ntawv lawm). Kuv kuj tau nqa thiab ua tib zoo muab me ntsis pleev nplaum tom qab txhua qhov tsoo "(kom nws tsau rau hauv daim ntawv me ntsis, yog li tsa qhov" tsoo "; ua kom zoo nkauj zoo nkauj. Nws tsis ua ntau, tab sis nws muaj peev xwm heev …IMHO.

Kauj Ruam 5: Ntxiv: Kev piav qhia ntawm Kev Ua Haujlwm

NPN transistor xav tau lub teeb liab mus rau Lub Hauv Paus kom tso cai rau hluav taws xob ntws los ntawm Collector mus rau Emitter, ua tiav qhov Circuit Court. Thaum qhov kev hloov pauv raug kaw, lub teeb liab nkag thiab LED los rau. Tib lub sijhawm, C1 raug them, thiab txij li DC yuav tsis hla C1, lub peev xwm tau khaws cia. Thaum qhov hloov pauv raug tso tawm, R1 ua rau qeeb ntawm C1 (tig rau ntawm lub transistor) thiab yog li nrog kev tiv thaiv me ntsis siab dua, LED nyob twj ywm ntev dua. Qhov no muaj tseeb, mus txog ib kis. Yog R1 yog TOO siab heev, lub teeb liab zoo txaus yuav tsis mus rau lub transistor kom qhib lub LED, tsis hais thaum lub pob raug thawb lossis tom qab nws tso tawm.
