Txoj haujlwm no qhia pom yuav ua li cas thiaj ua tau qee lub teeb yooj yim siv LED, ob lub khawm/saib cov roj teeb, daim kab xev npog thiab daim kab xev. Lub teeb Emitting Diodes (LED) muaj txiaj ntsig vim tias lawv lub zog qis, siv tau ntev, thiab cua sov tsawg. Cov teeb me me tuaj yeem tso rau ntawm koj lub tsho lossis lub kaus mom. Lawv yuav pab tib neeg pom koj thaum koj mus ncig thaum nws tsaus ntuj sab nraum.

Kauj Ruam 1: Qhov Chaw

Cov khoom siv sib xws: 1, Cov ntawv nplaum hlau me me clip2. daim kab xev npog (lwm hom kab xev yuav ua haujlwm tab sis kuv pom daim kab xev yooj yim siv) Cov khoom tsawg dua: 1. LEDs (daj thiab liab yog qhov kuv xaiv) Pob ntawm 20 cov khoom sib txawv ntawm LEDs ntawm Radioshack mus txog $ 3.00. Tab sis yog tias koj mob siab txog txo koj tus nqi yuav cov LEDs online. Muaj ntau tus neeg xa khoom online. Qhov Chaw Hluav Taws Xob Goldmine (qhov chaw nyiam kuv npaj yuav siv sai sai) muaj ntau pob khoom ntawm LEDs. Koj xav tau hom T1 thiab kuv xav tias 5mm loj yog qhov zoo. Kuv ntseeg tias liab, amber thiab ntsuab yog qhov pheej yig tshaj. 2. Cov roj teeb me me. Cov roj teeb no tau siv rau lub moos taug kev thiab tsis ntev los no lawv tshwm nyob rau hauv cov npav suab paj nruag tos txais. Kuv yuav ib lub pob tawm ntawm 24 rau kwv yees li $ 3.00. Yog li ntawd, nyob ntawm seb qhov ntau npaum li cas koj yuav tsum muaj peev xwm ua kom lub teeb qis dua li $ 1 txhua. Nco ntsoov tias cov hlau lead zoo ntawm lub LED ntev me ntsis tshaj qhov tsis zoo. Cov coj zoo thiab tsis zoo yuav tsum txuas nrog kom raug rau LED kom pom kev.

Kauj Ruam 2: Sib Sau Ua Ke

Tom qab muab lub LED tso rau ntawm ib daim kab xev kom cov hlau lead nyob ze rau ntawm daim kab xev, tso lub roj teeb rau ntawm cov hlau lead. Lub roj teeb twg yog 1.5 volts yog li ob lub roj teeb xav tau los teeb lub LED. Qhov zoo (+) feem ntau yog daim ntawv lo. Saib daim duab hauv qab no los pab koj txheeb xyuas qhov polarity ntawm lub roj teeb xaus. Nco tseg cov hmoov txhuas zoo yuav muaj qhov zoo ntawm lub roj teeb kov nws thiab cov hmoov txhuas tsis zoo yuav muaj qhov tsis zoo ntawm lub roj teeb kov nws.

Kauj ruam 3: Ua kom tiav Circuit Court

Cov ntawv hlau hlau yuav ua kom tiav cov Circuit Court los ntawm kev kov cov posive thiab sab tsis zoo ntawm cov roj teeb. Cov LED yuav tsum ci. Qhov teeb pom kev tiav tuaj yeem xav tias yog cov qhaub cij. Pib sab nraud yog daim kab xev nplaum, tom qab ntawd txheej txheej npog daim kab xev, ua raws los ntawm LED coj, tom qab ntawd roj teeb, thiab thaum kawg ntawm lwm sab ntawm daim kab xev. qee zaum tsis tsaws ntawm cov khoom kom raug thiab lub Circuit tsis ua tiav. Tsiv cov clip ncig me ntsis pab nrhiav nws hauv qhov chaw zoo. Cov kauj ruam tom ntej qhia thiab xaiv txoj hauv kev kom ua tiav lub teeb.

Kauj Ruam 4: Kev Xaiv Yeem

Hloov chaw ntawm kev siv cov ntawv txuas hlau kom ua tiav lub Circuit Court, ob lub roj teeb tuaj yeem nqa ua ke los ntawm daim kab xev npog. Qhov kawg thiab qhov tsis zoo yuav tsum tau nias ua ke. Cov ntawv nplaum tseem siv tau. Nws nias ib feem ua ke txij li daim kab xev tsis muaj zog txaus los tuav cov ntu nruj ua ke. Qhov kev xaiv cov txheej no yog: sab nraum daim kab xev kaw kab xev kab xev kab xev LED leadone roj teeb thib ob lub roj teeb thib ob LED leadmasking daim kab xev sab ntawm clip nias tawm tsam lwm tus sab tsis zoo.
