Cov kab hauv Circuit yog ib txoj hauv kev yooj yim thiab lom zem los qhia rau cov menyuam paub txog kev siv hluav taws xob thiab hluav taws xob thiab txuas lawv nrog cov ntawv kawm STEM. Kab laum ntxim hlub no suav nrog lub zog zoo thiab muaj tswv yim tsim txuj ci, ua haujlwm nrog hluav taws xob thiab hluav taws xob uas yuav ua rau koj cov menyuam nyiam thiab sib tw.

Cov haujlwm STEM no yog cov kauj ruam tom ntej rau Qhib thiab Kaw-Circuit. Yog tus menyuam muaj kev nkag siab txog kev qhib thiab kaw cov kab hluav taws xob, nws yuav nkag siab yooj yim nkag mus rau Series thiab Parallel Circuit. Hauv cov lus qhia no, Kuv tab tom ua haujlwm nrog cov khoom sib txuas. Koj kuj tseem tuaj yeem piav qhia txog kev sib tw nrog cov haujlwm no ib yam. Kuv xav tau txoj haujlwm uas yooj yim thiab muaj qhov suav tsawg, tab sis kuv xav kom nws nce qib me ntsis kom koom nrog pab pawg hnub nyoog dav dua. Cov dej num no zoo tshaj rau hnub nyoog 9 xyoos thiab tshaj saud. Ntxiv qee cov tshuaj ntxhua khaub ncaws thiab tsis muaj qhia txog yam tsiaj twg lawv yuav los nrog.

Kauj Ruam 1: Cov Khoom Uas Koj Xav Tau

1) 2 Teeb LED.

2) Insulated PVC coated hlau.

3) Roj teeb - CR2032 3V.

4) Daim Kab Xev Hluav Taws Xob.

5 Clothespins.

6) Pipecleaners/chenille sticks

7) Wirestripper.

8) Plier.

Kauj Ruam 2: Txiav thiab Tshem Tawm Txog Qhov Txheej Txheej

Yog tias koj muaj cov xaim tuab koj tuaj yeem siv xaim hluav taws xob tab sis yog tias koj muaj cov xaim xaim koj tuaj yeem txiav cov xaim siv txiab. Txiav koj cov xov hlau hauv qhov ntev sib npaug. Txiav tom qab ntsuas qhov ntev ntawm cov hlau sib npaug rau qhov ntev ntawm cov khaub ncaws. Nws raug nquahu kom txiav nws ntev me ntsis thiab txiav nws tom qab mus txog qhov ntev kawg. Koj xav tau qhov ntev txaus rau kev sib txuas zoo tab sis tsis ntau dhau uas koj nce koj qhov kev pheej hmoo ntawm kev cuam tshuam hauv Circuit Court. Kom cov tub ntxhais kawm txiav lawv cov xaim ua plaub daim sib npaug.

Qhia cov tub ntxhais kawm yuav ua li cas kom tshem tawm PVC txheej xiav kom nyab xeeb tawm ntawm qhov kawg ntawm lawv cov xov hlau nrog cov xaim hluav taws xob. Seem ob qhov kawg ntawm xaim ntev li 1.5 cm.

Kauj ruam 3: Terminals ntawm LED

LED sawv rau Lub Teeb Emitting Diode. Koj Tus Menyuam yuav tsum muaj kev paub txog cov dav ntawm LED thiab nws ci li cas. Ua ntej txav mus rau hauv Circuit Court, pib qhia koj tus menyuam tias "koj yuav pom ib txhais ceg ntev dua lwm qhov" Qhov ntev dua yog tus pin zoo (Anode), thiab luv dua yog tus pin tsis zoo (Cathode).

Muab ib sab ntawm LED tso rau ntawm txhua sab ntawm lub roj teeb. Nws puas teeb? Yog tsis yog, hloov ob sab. Qhov "ceg" ntev (anode) thiab ceg luv (cathode) tsuas yog ua haujlwm ib txoj hauv kev ntawm roj teeb. Cia cov tub ntxhais kawm sim ua kom paub seb txoj kev twg ua haujlwm.

Kauj ruam 4: Quav ob txhais ceg

Siv ob lub LEDs. Siv lub plier quav ob txhais ceg ntawm LEDs. Cov kauj ruam no yog txhawm rau xyuas kom yooj yim txuas ntawm cov xov hlau mus rau ob txhais ceg ntawm LED.

Kauj Ruam 5: Txuas Cov Hluav Taws Xob

Kom cov tub ntxhais kawm sib tw cov xov hlau nyob ib ncig ntawm qhov zoo thiab ceg tsis zoo ntawm ob lub LEDs. Ntawm no, Kuv tab tom siv lub plier ntswj cov ceg LED nrog cov xov hlau. Nco ntsoov kom muaj qhov sib zog khov kho kom tsis muaj qhov xoob txuas tom qab.

Kauj Ruam 6: Txheeb xyuas cov Terminals

Txheeb LEDs nrog roj teeb los ntawm kev kov cov xov hlau zoo rau ib sab ntawm lub roj teeb thiab sib tw cov xov tsis zoo rau lwm sab ntawm lub roj teeb. Yog tias nws tsis ua haujlwm, tig lub roj teeb dua. Rov ua qhov qub nrog lwm LED. Tam sim no, cov tub ntxhais kawm paub lub dav hlau twg yog qhov zoo thiab qhov twg yog qhov tsis zoo.

Kauj Ruam 7: Tso LEDs ntawm Clothspin

Kom cov tub ntxhais kawm tso ob lub LEDs ntawm ob qho kawg ntawm cov khaub ncaws. Muab cov LED tso rau hauv ib txoj hauv kev uas lub davhlau ya nyob twg zoo ntawm ob lub LEDs mus rau hauv Clothespin xaus thaum lub davhlau ya nyob twg tsis zoo ntawm ob lub LED mus sab nraum qhov kawg ntawm cov khaub ncaws. Cov LEDs tso rau ntawm qhov kawg yuav tsum nruj txaus kom tuav ntawm qhov kawg.

Kauj Ruam 8: Ruaj ntseg LEDs

Ruaj ntseg LEDs thiab xov hlau rau khaub ncaws nrog daim kab xev hluav taws xob. Qhwv ib ncig ntawm lub khaub ncaws kawg 4-5 zaug txhawm rau txhim kho LEDs thiab xov hlau nyob hauv qhov chaw.

Kauj Ruam 9: Lub Tswv Yim Tom Qab Parallel Circuit

Cov hluav taws xob hluav taws xob yooj yim muaj lub zog siv (Roj teeb), ua tiav txoj hauv kev kom cov hluav taws xob ntws mus (Cov xov hlau), thiab lub zog tiv taus. Ntawm no lub load tau sawv cev los ntawm LEDs. Yog tias muaj ntau dua ib lub nra (LED hauv qhov no) hauv Circuit Court, muaj ob txoj hauv kev uas lub thauj khoom (LEDs) txuas nrog.

• Parallel
• Series

LED yuav tsum txuas nrog ib qho txuas lossis txuas txuas. Nrog kev sib txuas sib txuas, cov ntsiab lus pib (+) thiab cov ntsiab lus kawg (-) ntawm cov khoom sib txawv sib txuas ua ke. Cov hluav taws xob sib txuas tau txais tib qhov hluav taws xob rau txhua LED. LED yog ib qho kev tivthaiv heev, nws tuaj yeem tawg ntawm qhov hluav taws xob siab. Yog li, tom qab qhov kev sib tham no, koj tuaj yeem qhia "Resistor" rau cov tub ntxhais kawm kom lawv nkag siab qhov tseem ceeb thiab xav tau tus tiv thaiv hauv Circuit Court. Siv 220 ohm lossis 330 ohm resister nrog lub davhlau ya nyob twg ntawm LEDs.

Siv tib kab kab, piav qhia ntu ntu rau cov tub ntxhais kawm. Nrog kev sib txuas ua ke tsuas muaj ib qho ntws. Tam sim no nkag mus rau thawj qhov chaw los ntawm + thiab tom qab ntawd dhau los ntawm - txav mus rau qhov chaw tom ntej thiab ua tib yam nrog qhov chaw thib peb.

Kauj Ruam 10: Txuas Qhov Zoo thiab Qhov Tsis Zoo

Siv lub tswvyim ntawm Parallel Circuit. Txuas ob qhov zoo ntawm LED thiab ob qho tsis zoo ntawm LED thiab ntswj lawv ua ke siv tus nplais.

Kauj Ruam 11: Txuas Roj Teeb

Muab cov roj teeb ntawm tes npib ntawm qhov tuav ntawm cov khaub ncaws. Qhov tuav yuav tuav lub roj teeb kom nruj. Tam sim no tso qhov sib tw qhov zoo thiab qhov tsis zoo ntawm LEDs sab hauv tuav ntawm cov khaub ncaws, txuas qhov zoo ntawm lub roj teeb nrog qhov zoo ntawm LEDs thiab qhov tsis zoo ntawm lub roj teeb nrog qhov tsis zoo ntawm LEDs.

Kauj Ruam 12: Ntxiv Kev Lom Zem

Thaum kawg, ntxiv cov tshuaj ntxhua khaub ncaws los tsim qee yam lom zem! Qhwv cov khaub ncaws nrog koj xaiv cov tshuaj ntxhua khaub ncaws, thiab ua ob txhais ceg. Kuv ua kab. Muab kev ywj pheej rau cov tub ntxhais kawm los ua txhua yam uas lawv xaiv. Ua nws muv, npauj npaim, lossis lwm yam. Cia lawv muaj tswv yim:)

Kauj Ruam 13: Koj Cov Kab Cuam Tshuam Tau Npaj Lawm

Tam sim no koj tus tub ntxhais kawm tau kawm kev sib tw sib tw nrog kev lom zem.. Ncua qhov kev sib tham piav qhia txog kev sib tw hauv Circuit thiab txaus siab rau:)

Muaj ib hnub zoo. Ua tsaug.
