Siv lub xov tooj qub them rau lub hwj chim saib zoo coj teeb. Kuv ua cov qauv ntawm qhov ntxoov ntxoo nrog lub tsheb kauj vab hloov pauv. Tsis tas li, txheeb xyuas qhov kev qhia no kom ua rau koj tus kheej lub log tig.

Txog kev tshoov siab, txheeb xyuas qhov duab ntawm cov teeb ua tiav.

Yog tias koj twb muaj cov LEDs muag rau cov neeg tawm tsam los ntawm ib qho ntawm peb cov khoom siv, koj tuaj yeem hla cov kauj ruam no. Txwv tsis pub, koj tuaj yeem ua haujlwm tawm qhov loj npaum li cas rau siv nrog Ohm txoj cai. V = IR Cia peb ua haujlwm tawm qhov kev tawm tsam loj npaum li cas peb xav tau rau LED nrog lub zog tom ntej ntawm 2.5V thiab siv tam sim no ntawm 20mA. Lub xov tooj them nyiaj nyob ib puag ncig 5V, tab sis tuaj yeem sib txawv yog li yog tias koj muaj lub multimeter koj tuaj yeem sim nws. Tshem tawm qhov hluav taws xob rau pem hauv ntej los ntawm lub xov tooj them khoom siv kom tau txais qhov hluav taws xob hla tus tiv thaiv = 2.5V. Tom qab ntawd ua haujlwm R = V / I = 2.5V / 20mA = 125Ohms. Txhawm rau ua qhov no, sib dhos ua ke cov ceg ntev ntawm ib qho LED nrog cov ceg luv ntawm lwm qhov, tom qab ntawd sim nrog lub xov tooj them nyiaj thiab xyuas seb lawv puas tsis ci lossis tsaus heev. Yog xav paub ntau ntxiv txog cov xov tooj sib txuas sib txuas ua ke, saib nplooj ntawv Wikipedia ntawm no.

hle cov xov hlau ntawm lub xov tooj charger. Feem ntau koj yuav muaj cov dub thiab xaim liab tab sis qee zaum koj muaj ntau dua. Koj yuav tsum nrhiav qhov twg yog hauv av thiab qhov twg yog qhov zoo.

Cais tag nrho cov xov hlau thiab thim rov qab ib qho me me ntawm lawv cov rwb thaiv tsev. Plug rau hauv lub xov tooj them nyiaj thiab tom qab ntawd sim cov LEDs ntawm cov xov hlau sib txawv kom txog thaum koj tau txais lub teeb ci LED. Txiav cov xov hlau uas tsis siv (yog tias muaj). Tom qab ntawd siv lub chocblock ntswj lub xov tooj ntawm tes them xov tooj thiab cov ceg LED ua ke. Koj tuaj yeem siv ob peb LEDs ua ke (saib daim duab) kom ua xim sib txawv. Qhov no tuaj yeem ua tau zoo heev li koj xav tau kom ntseeg tau tias LED ob txhais ceg tsis hla hla (uas yuav ua rau luv Circuit Court), thiab tias LED ob txhais ceg tau tuav ruaj khov hauv chocblock (txwv tsis pub ib lossis ob qho LEDs yuav tsis ua) lub teeb).

Xov hlau los ntawm lub qhov hauv lub chocblock thiab tom qab ntawd khoov nws hla thiab puag ncig kom lub chocblock raug ntes nyob hauv nruab nrab. Tom qab ntawd khoov cov hlau mus rau hauv V duab nrog chocblock ntawm qhov ntse kawg ntawm V.

Siv daim kab xev kom ruaj ntseg ob txhais ceg ntawm V mus rau cov ntaub pua plag lossis txhua yam uas koj siv rau lub hauv paus. Plug rau hauv lub xov tooj them nyiaj txhawm rau txheeb xyuas txhua yam tseem ua haujlwm vim tias tom qab peb tso qhov ntxoov ntxoo rau nws yuav nyuaj rau nkag mus.

Yog tias koj xav ntxiv qee cov ceg nkhaus, tom qab ntawd khoov me ntsis U cov duab nyob rau hauv qhov kawg ntawm cov xaim uas koj tuaj yeem nyem rau hauv lub raj xa ntawv. Tom qab ntawd ntxiv qee daim kab xev los tuav lawv hauv qhov chaw.

Thaum kawg, khoov qee cov curls zoo hauv qhov kawg.

Kauj Ruam 6: Ua Qhov Tsaus

Kuv siv lub tsheb kauj vab yoog raws ua kom zoo nkauj ntxig. Koj tuaj yeem tsuas yog txaws tus number case txog, lossis txawm tias txiav qhov hauv qhov ntxoov ntxoo kom ua rau cov duab ntxoov ntxoo zoo nkauj thiab duab ntxoo thaum lub teeb qhib.
