Ua lub teeb nyem yog lub sijhawm zoo rau siv qee qhov txuj ci hluav taws xob yooj yim. Nws yog txoj haujlwm zoo rau hnub so lossis txawm tias yuav ua hauv chav kawm. Txawm li cas los xij vim nws ib txwm siv cov hlau txuas hauv qhov ua tiav ntawm txoj haujlwm kuv tsis pom zoo kom cov menyuam ua qhov no yam tsis tau kev pab los ntawm tus neeg laus.

Nov yog qee cov lus qhia uas pom thawj zaug zoo li nyuaj tab sis qhov tseeb lawv yog qhov yooj yim heev. Kuv theorized ob peb kauj ruam rau lub hom phiaj didactic. Tsis muaj coiling, wb ua nws.

Kauj Ruam 1: Yam Koj Yuav Tsum Tau

• LED (hauv kuv rooj plaub dawb)

• Resistor (nyob ntawm LED xim)

• Roj teeb 9V

• Snap conector 9v

• Soldering Hlau

• Hlau

• BEP toggle hloov

Cov khoom no feem ntau pheej yig thiab yooj yim nrhiav

Kauj ruam 2: Tsim Circuit Court

1. To tsim lub teeb nyem Circuit Court kuv xaiv txuas dawb LED's hauv paralel. Txog qhov no koj yuav tsum nkag siab tias txhua tus LED muaj ob lub dav hlau, qhov me me tsis zoo thiab qhov loj yog qhov zoo. Yog li kuv tau siv tag nrho qhov tsis zoo mus tasheter.

Kauj Ruam 3: Xam qhov raug thiab xaiv tus tiv thaiv

2. Txhua lub davhlau ya nyob twg zoo tau muab tso rau hauv lub resistor. Txhawm rau xaiv tus tiv thaiv koj yuav tsum paub:

• qhov hluav taws xob ntawm lub hwj huam mov, piv txwv li. pes tsawg volts koj yuav siv los txhawb koj lub LED, • qhov hluav taws xob txhawb los ntawm koj cov LED hauv volts, • tam sim no txhawb los ntawm nws cov LED hauv amps.

Cov ntaub ntawv no yuav nyob ntawm LED xim (rooj 1). Txhawm rau xam qhov tseeb resistor nws yog qhov yuav tsum tau siv cov mis:

R = (Vpower supply -Vled) / Kuv

R = yog qhov tsis kam nyob hauv ohms

Vpower mov = yog qhov hluav taws xob hauv volts ntawm lub zog siv (roj teeb)

V coj = yog qhov hluav taws xob hauv volts ntawm LED

Kuv = yog LED tam sim no hauv amperes

Piv txwv li, hauv kuv qhov xwm txheej kuv tau xaiv siv lub LED dawb rau lub teeb nyem. Yog li, Yog tias peb hloov qhov txiaj ntsig ntawm cov mis peb yuav pom

R = (9 - 3) / 0, 02

R = 6 / 0,02

R = 300 ohms rau txhua LED

Kauj ruam 4:

Txawm li cas los xij kuv tsis tuaj yeem pom 300 ohms resistor só Kuv xaiv rau 330 ohms resistor feem ntau pom. Yog li tau hais, Kuv tau siv 330 resistor ohms hauv txhua lub davhlau ya nyob twg zoo thiab txuas txhua tus tiv thaiv ua ke. BEP toggle hloov tau txuas rau ntawm lub davhlau ya nyob twg tsis zoo. Txhawm rau ua kom tiav cov Circuit Court Kuv tau siv tag nrho ntawm qhov txuas txuas. Zoo li ntawm daim duab saum toj no.

Kauj ruam 5: Rooj plaub

Thaum kawg kuv muab txhua yam khoom no tso rau hauv lub raj. Cov kauj ruam no yog nyob ntawm yeem, tab sis rau kuv ua tau siv lub teeb nyem Thaum los nag. Lwm qhov xwm txheej tuaj yeem ua los ntawm cov kav dej lossis cov tin ntawm altoids
