NCO TSEG: THAUM KAWG THAUM KAWG YOG INTRO. THOSE NTAWM KOJ KUV YUAV TSUM PAUB NTAWV txog LED's YUAV TSHUAJ HNUB TEEB MEEM 4 THIAB 5 RAU COV HAUJLWM. feem ntau) tsis tshua paub txog LED's. Tsis muaj leej twg hauv kuv chav kawm txuj ci hauv tsev kawm ntawv ib txwm tau hnov txog lawv. Nov yog cov lus qhia yooj yim rau LED's uas yuav tsum qhia koj cov hauv paus. Nws zoo yog tias koj txaus siab tab sis tsis muaj lub tswv yim yuav pib qhov twg. Kuv kuj xav tias qhov no yuav pab tawm leej twg xav nkag rau hauv kev sib tw, tab sis nws coj kuv ib pliag kom tiav. Nco ntsoov, (Raws li ib txwm muaj) kev tawm tswv yim thiab kev ntaus nqi (zoo lossis tsis zoo) yeej ib txwm muaj txiaj ntsig! Rau cov ntaub ntawv ntau ntxiv tshwj xeeb rau WIRING, Koj tuaj yeem pom NOAHW Cov Lus Qhia "LEDs Rau BEGINNERS"

Kauj Ruam 1: Npe/Cov Ntaub Ntawv Yav Tom Ntej

LED cov. Yog li feem ntau ntawm Cov Lus Qhia. Dab tsi yog heck yog lawv? LED yog lub npe luv rau Lub Teeb Emitting Diode. Zoo, koj nug, dab tsi hauv ntiaj teb yog diode. Lub diode yog lub cuab yeej uas, hauv cov lus yooj yim tshaj plaws, tso cai rau hluav taws xob ntws los ntawm ib txoj kev tab sis tsis yog lwm qhov. Cov ntawm koj uas tau paub txog cov khoom siv dag zog tuaj yeem xav txog nws zoo li lub tshev kos. Yog tias koj tsis muaj kev paub siv tshuab, tsis quav ntsej kab lus kawg tam sim no uas koj paub tias lub diode yog dab tsi, LED tsuas yog ib qho uas tso tawm lub teeb (Tab sis koj tuaj yeem zaum paub qhov ntawd tsuas yog los ntawm kev nyeem lub npe).

Kauj Ruam 2: Cov Lus Qhia Tseem Ceeb Ntxiv

Lwm qhov tseem ceeb ntawm txhua tus LED (thiab txhua lub diodes) yog tias txhua tus ntawm lawv muaj ob lub electrodes. Cov no yog qhov tseem ceeb kom paub thaum koj txuas lub LED mus rau hauv Circuit Court. Lawv yog … Anode - P -sab uas yog txhais ceg ntev dua. Thiab qhov … Cathode - Uas yog n -sab thiab luv dua ceg. Txij li koj paub cov lus no koj tuaj yeem nco tau tias hluav taws xob ntws tau yooj yim los ntawm qhov anode mus rau cathode tab sis tsis yog lwm txoj hauv kev.

Kauj Ruam 3: Qhov zoo ntawm LED

LEDs zoo rau ntau qhov laj thawj. Ua ntej tshaj plaws, lawv tsis ua kom sov li lub teeb pom kev zoo ib txwm ua. Qhov no yog qhov zoo vim tias, zoo, koj tsis hlawv koj tus kheej. Lawv kuj tseem me dua lub teeb nrig. Lwm qhov tseem ceeb ntawm LED's yog tias lawv ua haujlwm ntawm cov hluav taws xob tsawg heev, uas yog qhov muaj txiaj ntsig vim tias nws ua rau lawv muaj kev nyab xeeb los ua haujlwm nrog (koj tsis tua hluav taws koj tus kheej). Feem ntau khiav ntawm 20mA.

Kauj Ruam 4: Cov Lus Qhia

Ib yam li nrog txhua yam, muaj qee cov lus qhia uas tau pab kom ntseeg tau tias koj cov LED ua haujlwm tau zoo. Qhib cov coj - Yooj yim, Kuv paub, tab sis tib neeg tsis nco qab. Qhov no yog qhov tseem ceeb vim tias nws tiv thaiv lawv los ntawm kev tsoo mus rau lwm qhov thiab ua rau koj lub hauv paus tawg. Nws yog diode; tam sim no tsuas yog ntws los ntawm nws ib txoj kev. Nyeem lub pob - Yooj yim dua, tab sis txhua tus LED xav tau qhov sib txawv me ntsis ntawm qhov hluav taws xob thiab qhov ntim.

Kauj ruam 5: Resistors

Nws ib txwm pab xaim tus tiv thaiv rau hauv koj lub Circuit Court. Nws yuav ua rau LED ntev dua los ntawm kev tso qhov hluav taws xob. Muaj qee qhov chaw uas ua rau nws yooj yim mus nrhiav tus tiv thaiv uas koj xav tau. Kuv nyiam nyob ntawm no.

Kauj Ruam 6: Cov Tswv Yim Tswv Yim

Tam sim no koj muaj qee qhov kev paub ntawm LED's yog dab tsi koj yuav xav tau qee cov tswv yim ua haujlwm. Nws yooj yim. Txhua yam uas muaj teeb pom kev. Thiab nws tseem tsis txwv rau qhov ntawd. Koj tuaj yeem tshawb xyuas qhov Kev Sib Tw LED rau qee lub tswv yim. Cov Lus Qhia uas kuv xav nkag mus rau hauv kev sib tw yog "Cov Lus Nco" uas yog lub rooj me me nrog cov lej ntawm ntu (kuv muaj plaub) uas koj muab tso rau hauv kom ceeb toom koj kom ua lawv. Txhua ntu teeb pom xim txawv. Lub tswv yim yog tias koj qhib txhua lub teeb thaum koj muaj qee yam uas koj yuav tsum nco ntsoov ua, tom qab ntawd kaw thaum koj ua tiav qhov ntawd. Kuv xav siv nws los nco txog kuv daim npav xyaum ua, xaiv suab paj nruag thiab lwm yam. Ib qho ntawm kuv lub tswv yim nyiam hauv kev sib tw yog Star Wars Blaster, uas qhib tag nrho lwm thaj tsam ntawm cov tswv yim phiaj xwm.

Kauj ruam 7: Tam sim no koj tau npaj lawm

Nrog cov "Cov Lus Qhia Cuab Yeej" (sorta) thiab ua tiav LEDucation (thov txim, tsis tuaj yeem tiv taus) Kuv vam tias koj tuaj yeem tawm mus thiab tsim qee qhov project LED txias. Nco ntsoov, Kuv yeej txaus siab rau txhua hom kev tawm tswv yim lossis kev ntaus nqi.
