Kuv nyob qhov twg, peb nquag mus yam tsis muaj hwj chim 3-8 teev ib zaug. Nws tuaj yeem tau txais kev thab plaub thiab kim khiav cov roj teeb rau lub teeb thiab hlawv tswm ciab tsuas yog lub tswv yim tsis zoo. Rummaging los ntawm Cov Lus Qhia Kuv pom MooseTooths txoj haujlwm, thiab txawm hais tias kuv nyiam nws, nws zoo li qhov ua tau zoo tuaj yeem txhim kho zoo nrog kev hloov LED, tab sis leej twg xav tawm tsam nrog kom tau txais qhov sib txawv ntawm LED txoj cai hauv qhov tsaus ntuj? Peb yuav saib xyuas qhov ntawd.

Kauj Ruam 1: Qhov Teeb Meem Tsis Zoo

Teeb Meem Teeb Meem
Teeb Meem Teeb Meem

Qhov teeb meem ntawm polarity tau daws los ntawm kev tsim tus choj rectifier. Peb feem ntau xav txog cov rectifiers hauv kev nkag siab hloov AC rau DC, tab sis lawv kuj tseem tuaj yeem siv tau yog tias qhov tsis paub meej ntawm lub hauv paus tsis paub. case. Ob qhov chaw ntawm diodes, qhov tseeb qhov kuv siv yog CFL's, cov lus qhia rau kev tshem tawm tau tshaj tawm los ntawm Westfw.

Lub caij nplooj ntoo hlav ntawm lub teeb roj teeb tuaj yeem ua rau muaj kev ntxhov siab los muab cov khoom rau. Kuv tau txiav txim siab tias cov yeeb yaj kiab yog cov tshuaj zoo tshaj plaws. Lawv tau hais txog qhov muag ntawm cov tswv yim ntawm tus choj diode thiab khoov kom haum rau lub roj teeb.

Yog tias koj xav kom raug qhov tseeb ntawm qhov no, koj tuaj yeem ntsuas qhov ntsuas hluav taws xob poob los ntawm tus choj txhawm rau suav qhov ntsuas qhov tseeb uas koj xav tau. Kuv tsis tau thiab muab ob 68 ohms sib dhos kom tau 34 ohms.

Kauj ruam 4: LED

Kuv muaj cov ntxim hlub me me 10 hli LEDs los ntawm Alan Parekh, uas yog qhov ci heev, tab sis kuv tsis tsuas yog xav tau qhov chaw ntawm lub qab nthab thiaj li ua raws li tus txiv neejfrom7up cov lus qhia kuv nthuav LED.

Kuv txuas tus LED resistor combo rau tus choj, nco ntsoov, ntawm no qhov teeb meem polarity. Tam sim no peb muaj cov kab hluav taws xob uas peb tuaj yeem tso rau ntawm lub roj teeb, hauv qhov tsaus ntuj yam tsis xav txog qhov sib txawv thiab qhov ntawd yuav muab qhov chaw nruab nrab ntawm 10-15 hnub ntawm lub teeb.
