Kuv txaus siab rau kev ua hauj lwm nrog koj ob txhais tes? Electronics rau tus cawm!

Electronics, xws li hluav taws xob khoom siv, cia li tsoo rau hauv ib tug neeg lub neej thiab yog li ntawd, nrees entrenched nyob rau hauv nws, nws tsuas yog tsis yooj yim sua xav txog tej yam lub neej tsis muaj xws li ib tug loj ntawm pab kiag li lawm. Piv txwv li, cov laus tiam yuav tsis ua li cas tsis TV, txhua txhua hmo lawv siv nyob rau hauv TV cov ntxaij vab tshaus, absorbing qhia thiab xab npum operas. Meanwhile, cov hluas lub pob ntseg tsis ottyanesh los ntawm laptops, ntsiav tshuaj, smartphones, tag nrho cov ntawm lawv mloog thiab tseem ceeb heev zog absorbed los ntawm lub ntiaj teb dav Web hu ua hauv Internet. Tab sis li cas ib txhia 50-60 xyoo dhau los tsis yog txhua tus neeg hauv tsev neeg muaj ib tug xov tooj cua, cia nyob ib leeg TV poob lawm. Progress tsis sawv tseem, nws rushes rau pem hauv ntej tsis yog los ntawm leaps thiab ciam teb, thiab bursts rau hauv txhua txhua lub tsev zoo li ib tug cua daj cua dub, kev rhuav tseg cov npaj cov me nyuam yaus ntawm tib neeg lub neej thiab ua rau lawv tsis meej pem nyob rau hauv daim ntawv ntawm cov hluav taws xob seev thiab pab kiag li lawm.

Txawm li cas los, feem ntau cov neeg no cia li cov neeg siv ntawm xws khoom, lawv tsis muaj ib tug clue txog yuav ua li cas rau tsim ib tug kev ntaus ntawv, los ntawm dab tsi hauv paus ntsiab lus nws ua hauj lwm. Kev paub txog cov neeg zoo li tas rau txoj siav nyob rau hauv cov ntaus ntawv mus rau lub network los yog mus rau muab tso rau hauv ntxiv xwb. Tab sis qhov no science yog heev nthuav thiab entertaining, thiab nws tsis yog yooj yim los mus kawm yuav ua li cas ua ib tug yooj yim ntaus ntawv nrog koj ob txhais tes. Electronics yuav koj qhib nrog rau lwm cov tes. Muaj mastered rau tsim, koj yuav tsis xav mus nyob rau ntawm qhov chaw, koj yuav muaj thiab txhawb lawv Tshuag ntawm kev txawj ntse, kom lawv txawj.

Ntawm cov hoob kawm, ib tug yuav tsum pib nrog qhov nyuaj kiag li lawm. Yog li ntawd, thaum nej tau sau ib lub tsev daim duab ntawm ib tug pa tswb ntawm qhov rooj nrog koj ob txhais tes, uas yuav muab electronics, txawv los ntawm tag nrho cov lwm yam zaus ntawm lub suab los yog suab paj nruag, koj xav tias ntseeg thiab koj yuav hloov mus rau ntau pab kiag li lawm.

Cia saib yuav ua li cas qhov no yog ua nyob rau hauv xyaum. Yuav kom sib sau ua ke peb yuav tsum tau ob resistor (22 ohms thiab 180 ohms), ib tug FET Ner310 capacitor 50-25 nyob rau hauv ib tug khawm, ib tug hais lus thiab ib lub hwj chim qhov twg los 9 volts. Nyob rau hauv no cov tswvyim, ntxiv rau qhov mov voltage thov ntawm ib tug resistor (22 ohms) thiab ib tug khawm rau cov kev tswj electrode ntawm cov transistor, lub passageway los ntawm kev uas lub resistor (180 ohm) thiab zoo puab. Tsis zoo puab yog kev cob cog rua rau ib tug voltage qhov chaw. Lub capacitor yog kev cob cog rua ntawm qhov tsis zoo davhlau ya nyob twg thiab lub transistor qhov chaw. Xws li ib tug tswvyim yog yuav mus rau tsib feeb, cia nyob rau hauv caug.

Koj muaj peev xwm yuav ib tug oob khab cov khoom siv xov tooj cua cov kws kho thiab kawm tau ib ntau yam ntawm lub tsev-ua rau koj tus kheej txhais tes, electronics uas yuav haum rau koj ib tug ntev lub sij hawm. Ntxiv mus, qhov zoo ntawm cov khoom xws li yuav ua tau zoo npaum li cas tshaj Suav counterparts, dej nyab peb khw muag khoom noj. Tsis kawg nyob rau hauv koj xyaum ua yuav coj tsheb electronics, tau nrog nws tus kheej txhais tes. Qhov kom zoo dua ntawm no qauv yog tias txhua yam nyob yog yooj yim heev, thiab ua hauj lwm yog sib ntaus sib tua rau "tej daim" ib tug ntau ntawm cov nyiaj.

Piv txwv li, muab nws tus kheej ntxiv LED teeb pom kev zoo nyob rau hauv lub tsheb: nyob rau hauv lub hood, nyob rau hauv lub nra compartment nyob rau hauv lub hav zoov ... los yog cia tus LED sawb rau hauv qab ntawm lub tsheb. Qhov no tsis yuav tsum tau tej kev paub. De rau lub xov tooj cua LEDs nrog ib lub mov voltage ntawm 12 V. Niaj hnub no, cov khoom no yog hais nyob rau hauv ib tug ntau yam. Yuav muab diodes nyob rau hauv lub vaj tse, kev tiv thaiv los ntawm hmoov av, av, dej thiab lwm yam A xws ntaus mounted elementary -. Nyob rau hauv ob npaug rau-mog daim kab xev.

Nyob rau hauv txhua lub tsheb nyob rau hauv lub hood thiab lub nra compartment muaj nyees khawm rau qhib, ntawm no mus rau lawv thiab nws yog tsim nyog mus cuag tus zoo lead ntawm lub LED, thiab qhov tsis zoo - rau lub tsheb lub cev. Nyob rau hauv xws li ib tug tswvyim mus cuag qhov kaj yeej yuav tsum zes tsuas yog thaum lub teeb yog muab rau, piv txwv li thaum lub sij hawm hmo ntuj. Yog hais tias koj tsis nyiam txoj kev no, rub lub roj teeb lub hwj chim thiab teem ib tug ntxiv khawm. Tab sis yuav ua li cas yooj yim yog hmo ntuj mus nrhiav ib yam dab tsi nyob rau hauv lub cev los yog khawb nyob rau hauv lub hood. Thiab feem ntau cov tseem ceeb - koj yuav ua li cas nws nrog nws tus kheej txhais tes. Electronics - Klondike yog cia li tag nrho cov hom ntawm cov tswv yim rau simulation thiab nyob.

Koj muaj peev xwm txawm qhia koj tus me nyuam kev txawj ntse no los yog kawm nrog nws. Qhov no yuav pab tau koj tsim kom muaj ib tug nyob ze kev sib cuag nrog nws tus tub, vim hais tias cov tub hluas zoo li tshwm nyob ib ncig ntawm nyob rau hauv ib daim ntawm cov hlau, sau ib tug ntau yam ntawm seev nrog lawv ob txhais tes. Electronics, los yog es, txoj kev paub nyob rau hauv cov cheeb tsam no, nws tsis yog ib yam dab tsi uas yuav tsum tau - desperately xav tau!
