Kuv thawj qhia! Nov yog qee yam kuv tau xub tsim rau tus phooj ywg uas tseem siv nws. Nws ua haujlwm zoo heev ntawm kev ntxiv lub teeb pom kev zoo rau chav tsaus. Kuv tau ua cov lus qhia no vim tias kuv txiav txim siab ua ib qho los da dej hauv kuv lub tsev. nws yog lub teeb hmo ntuj zoo meej. Nws khiav ntawm 12v phab ntsa adapter, yog li koj tsis tas yuav txhawj xeeb txog kev hloov roj teeb.
Kauj Ruam 1: Yam Koj Xav Tau
Yog li ntawm no yog yam koj xav tau rau txoj haujlwm no: [Soldering hlau, tau kawg… thiab cov laug]- 100k Resistor- 1K Resistor- NPN Switching transistor (2N4401)- Photo Cell- 3v LED- 12v phab ntsa adapter (saib ib ncig… Kuv paub tseeb koj tau txais ib qho!) Yeem tau:- Lub rooj tsav xwm me me (ua kom yooj yim dua!)- SPDT Hloov (kom ua tiav kev sib txuas)
Kauj ruam 2: Schematics
Raws li tau hais yav tas los, lub Circuit Court yog yooj yim heev. Lub transistor hloov dab tsi tshwm sim nrog LED. Yog tsis muaj nws LED yuav qhib thaum lub teeb qhib thiab qhov ntawd yuav tsis muaj txiaj ntsig. 100k resistor txwv ntau npaum li cas lub teeb xav tau los tua nws, thiab 1K resistor txwv cov nqi hluav taws xob mus rau LED. Koj tuaj yeem sim nrog qhov sib txawv resistor qhov tseem ceeb. Hauv qhov haujlwm no kuv siv ob 100K tus tiv thaiv vim kuv xav kom lub teeb pom kev hmo ntuj kom nkag siab ntau dua thiab nyob twj ywm hauv qhov pom kev ib puag ncig. Koj tuaj yeem yooj yim hloov cov no nrog qhov sib txawv tiv taus, zoo li lub lauj kaub me me, kom koj txiav txim siab qhov kev nkag siab thaum twg koj xav tau. Koj kuj tseem tuaj yeem hloov pauv 1K tus neeg tawm tsam, tab sis tus nqi qis dua yuav ua rau qhov siab tshaj plaws ci me ntsis rau qhov tsaus ntuj. Kuv kuj tseem siv 3 lub LED dawb rau txoj haujlwm no hloov ib qho (uas tsis ua haujlwm zoo ib yam li kuv vam tias, lo rau ib qho).
Kauj Ruam 3: Muab Nws Ua Ke
Ua raws li schematics yog qhov yooj yim zoo nkauj. Cov duab hauv qab no qhia tus txheej txheem, suav nrog cov kab hauv qab ntawm daim phiaj me me uas kuv tau siv.
Kauj Ruam 4: Muab Lub Hwj Chim
Tam sim no koj yuav xav coj koj li 12v adapter, thiab ntsuas qhov ntev ntawm cov xaim koj xav tau. Txoj kev kuv teeb tsa nws, lub rooj sib tham me me nyob sab xis ntawm nws thaum nws ntsaws kom lub teeb ci ntsa iab ntawm LED thiab ua rau chav zoo nkauj. Thaum koj tau txais nws ntawm qhov ntev zoo, hle kab xaim me ntsis kom koj tuaj yeem yooj yim muab nws tso rau hauv qhov chaw. Qhov no tseem ceeb! Koj yuav xav tau sau tseg ntawm polarity ntawm txhua cov hlau thiab lawv mus qhov twg. Ib qho nrog kab txaij dawb yog qhov zoo thiab dub dub yog qhov tsis zoo. Thaum koj tau teeb tsa qhov sib txawv, tsuas yog xaim nws raws li cov txheej txheem. [Yog tias koj xaiv ntxiv rau ntawm qhov hloov pauv, tsuas yog xaim xaim ntawm qhov zoo lossis tsis zoo xaim thiab lub rooj tsavxwm)]
Kauj Ruam 5: Txuas Nws - Koj Ua Tiav
Txuas nws thiab npog lub xov tooj ntawm tes, tshwj tsis yog koj nyob hauv chav tsaus. Cov LEDs yuav tsum tuaj! Whoooooo. Tam sim no koj tuaj yeem nrhiav txoj hauv kev kom tau txais lub rooj tsavxwm nyob saum lub adapter. Kuv tau laum ob lub qhov nyob rau sab saum toj ntawm lub adapter thiab ntsia nws rau hauv qhov chaw, tab sis kuv tsis tuaj yeem hais tias kuv pom zoo qhov no: P Kub kua nplaum ua haujlwm zoo xwb.

Koj tuaj yeem hais nws yog rau koj tus kheej kev nyab xeeb yog tias koj sawv thaum hmo ntuj thiab sim ua kom lub qhov rooj nyab xeeb. Tau kawg koj tuaj yeem siv lub teeb rau ntawm lub txaj lossis lub ntsiab lus tseem ceeb
