Nyob Zoo Sawv Daws, Hauv Cov Lus Qhia no, peb yuav ua lub teeb pom kev TV uas tig tau thaum tsaus ntuj.
Lub teeb tsis ncaj ncees no yog cov cuab yeej yooj yim uas tuaj yeem ntxiv rau txhua lub TV nrog lub hom phiaj ntawm teeb pom kev ntawm phab ntsa tom qab TV. Qhov kev pom kev no txo qis qhov pom kev pom ntawm cov zaub, txo qhov muag qhov muag thiab qaug zog uas tshwm sim thaum saib lub teeb pom kev zoo tiv thaiv keeb kwm yav dhau tsaus ntuj rau ntau lub sijhawm.
Ib qho ntxiv, nws tseem ua rau pom qhov dub thiab sib piv ntawm cov zaub ua cov xim ntawd kom koj tuaj yeem txaus siab rau kev saib zoo dua, txawm tias nyob hauv TVs pheej yig dua.
Khoom siv
Cov cuab yeej thiab cov ntaub ntawv xav tau los ua txoj haujlwm no (cov koom nrog sib txuas):
- Soldering hlau -
- Photoresistors (LDR) -
- 2N2222 NPN Transistors -
- Asorted resistors -
- LED Sawb -
- Protoboard -
- DC Jack -
- 12V fais fab adapter -
Kauj Ruam 1: Lub hauv paus ntsiab lus ntawm Kev Ua Haujlwm
Lub teeb pom kev yog tsim tawm ntawm ob peb yam tab sis lub hnub qub tseem ceeb ntawm txoj haujlwm yog LDR lossis lub teeb-nyob ntawm tus tiv thaiv. Feem ntau hu ua photoresistor, cov cuab yeej no muaj qhov nkag siab zoo rau saum thiab nws hloov pauv nrog kev hloov ntawm lub teeb ntawm nws. Qhov ntau lub teeb nws tau txais, qis nws ua haujlwm.
Lub Circuit Court siv ib LDR, 1 150K Ohms resistor, thiab 2 2n2222 lub hom phiaj dav dav transistors. LDR thiab tus tiv thaiv tsim lub teeb pom kev sib faib hluav taws xob uas yuav tig rau thawj lub transistor sai li sai tau thaum LDR muaj kev tiv thaiv siab dua li thaum lub teeb nyob ib puag ncig qis.
Qhov no ces tig rau ntawm lub transistor thib ob uas tsuas yog siv los hloov pauv rau LED sawb. Koj tuaj yeem siv hluav taws xob nrog tsuas yog ib qho transistor nkaus xwb, tab sis qhov xwm txheej ntawd, kab txaij yuav tsis siv nrog 12V puv los ntawm kev nkag vim yog qhov faib hluav taws xob.
Kauj ruam 2: Npaj Circuit Court
Thaum kuv tau npaj lub voj voog, kuv tau rov ua dua nws ntawm ib daim ntawv ntawm daim txiag ntoo, ua kom ntseeg tau tias tawm ntawm LDR ob txhais ceg saum toj kom ntau li ntau tau. Cov no yuav tom qab pab peb tso LDR nyob rau hauv ib txoj hauv kev uas lub teeb los ntawm kab txaij tsis cuam tshuam rau nws, tab sis nws tau txais nws lub teeb ci los ntawm qhov pom kev ib puag ncig hauv chav.
Kuv kuj tau ntxiv DC jack rau hauv Circuit kom txhawb nws nrog 12V phab ntsa txuas thiab kuv tso cov xov ntev dua qhov twg LED sawb xav tau txuas. Cov no yuav txuas nrog tom qab thaum kuv rub kab txaij nyob tom qab ntawm TV.
Kauj Ruam 3: Xeem Circuit
Ua ntej qhov kev sib dhos zaum kawg, Kuv tau ua kom kuaj lub Circuit Court ntawm kuv lub rooj ntev zaum kom paub tseeb tias txhua yam ua haujlwm raws li qhov xav tau.
Kauj ruam 4: Nruab nws hauv TV
Thaum kuv tau npaj txhua yam, kuv tau txav txhua yam mus rau kuv chav nyob, thiab siv cov nplaum ntawm cov hlua LED kuv tso nws nyob ib puag ncig ntawm TV. Nco ntsoov siv daim kab xev LED nyob rau hauv ib txoj kev uas nws yuav tsis pom los ntawm sab xub ntiag lossis ob sab, vim nws tsuas xav tau kom pom lub phab ntsa tom qab TV.
Kuv kuj tseem siv kuv rab phom kub kub txhawm rau ntxiv qee qhov txhawb nqa rau cov hlua LED hauv ob peb qhov chaw thiab tseem txhawm rau teeb tsa cov khoom siv hluav taws xob mus rau hauv qab kaum sab laug ntawm TV.
Raws li cov kauj ruam kawg, Kuv tau txiav thiab siv cov xaim hluav taws xob tawm ntawm lub rooj tsavxwm mus rau kab txaij LED thiab kuv siv nws los ntsuas thiab saib nws ua haujlwm li cas.
Kauj Ruam 5: Xeem Kev Txhim Kho
Txij li nws yog lub sijhawm nruab hnub thiab muaj lub teeb ci ntau lub sawb tsis qhib tab sis sai li sai tau thaum kuv npog LDR nrog kuv txhais tes, cov kab txaij tau siv zog raws li qhov xav tau.
Kauj ruam 6: Txaus siab rau
Qhov tseeb ci ntsa iab ntawm qhov haujlwm tuaj thaum hmo ntuj thaum peb tua lub teeb thiab cov kab txaij tig rau qhov pom kev txaus ntshai.
Yog tias koj nyiam txoj haujlwm no nco ntsoov muab nws lub siab, nco ntsoov sau npe yuav ua rau kuv li YouTube channel, txheeb xyuas kuv lwm Cov Lus Qhia, thiab kuv yuav ntsib koj hauv ib qho ntxiv.
