Lub LED sib txawv ntawm lub qhov muag teeb nyob hauv uas nquag hloov thiab tua tsis ua rau nws lub hnub nyoog luv. Qhov no tso cai rau nws siv nrog rau kev rhuav tshem tam sim no yam tsis muaj kev ntshai ntawm kev puas tsuaj.
Cov Lus Qhia

Qhov yooj yim tshaj plaws los ua cov tsom ntsais teeb LED yog nrog lub hauv paus tsev sib tsoo. Txhawm rau ua qhov no, thov voltage rau nws hauv polarity ncaj qha. Qee qhov diodes no tau muaj cov thaiv teeb tsa kom tsim nyog kom thiaj li muaj peev xwm muab nrog txog plaub qhov hluav taws xob tsis muaj qhov ntsuas sab nraud. Tab sis nco ntsoov tias lawv tseem muaj rov qab polarity tiv thaiv diodes. Yog tias koj txuas lub LED rau lub hauv paus tsis raug, thiab tib lub sijhawm tsis siv cov khoom tiv thaiv, cov diode tiv thaiv yuav ua kom sov thiab yaj lub teeb ci. Txhawm rau tiv thaiv qhov no los ntawm tshwm sim, thaum kuaj xyuas qhov polarity ntawm xws li LED, siv lub ntsuas tsis txhob poob. Ua tib yam nrog cov lus muab hluav taws xob ntau dhau plaub qhov hluav taws xob, thiab kuj yog tias koj tsis paub yog tias muaj cov tiv thaiv kab hluav taws xob hauv qhov hluav taws xob LED.

Los ntawm kev ua haujlwm tig mus rau hauv thiab tawm, lub breaker hauv blinking LED modulates tam sim no noj ntawm lub cuab yeej raws li. Qhov no tso cai rau nws siv los cuam tshuam tam sim no los ntawm ob lossis peb ntau cov xaim LED. Tig lawv, saib cov polarity, hauv kab xwm nrog flashing. Nyob rau tib txoj saw, txuas lub resistor hauv series, thiab nce rau qhov muab qhov hluav taws xob kom nws txaus los qhib txhua lub LED. Ib txwm LEDs yuav nyem ntawm sync nrog lub ntsais teeb.

Muaj qee kis, nws yog qhov yuav tsum tau tias lub LED tsis ntsais tsis synchronously, tab sis nyob rau hauv qhov tsis sib xws. Hauv qhov no, txhua tus ntawm lawv yuav tsum ntsais. Txuas lawv rau hauv parallel, kev saib xyuas lub polarity. Yog tias lawv xav tau cov tawm tsam, txuas ib ntu nrog txhua.

Koj tseem tuaj yeem ua tus blink LED nyob rau lwm txoj kev. Qhov feem ntau ntawm cov no yog kev siv RC generators, txwv tsis pub hu ua multivibrators. Lawv muab faib ua kom sib txig sib luag, tsis sib luag thiab ua rau cov khoom muaj kuab. Sim, tshwj xeeb, txhawm rau txhim kho lub tshuab hluav taws xob zoo no raws li daim duab uas qhia hauv daim duab no. Hauv qhov no, ob lub LEDs yuav nyem hloov.

Yog tias koj tab tom tsim tus qauv uas suav nrog Arduino firmware platform lossis zoo ib yam, tsis txhob siv cov khoom ntxiv los ua kom nws pom. Txuas nws los ntawm cov tsis xws leej twg nrog lub anode mus rau qhov zoo ntawm lub hwj chim sib txuas lus thiab cathode rau cov maub los tso tawm, lossis nrog cathode rau ntawm cov xaim uas nquag thiab lub anode rau tus tswj hwm cov zis. Hauv thawj kis, nws yuav ci ntawm lub voj voog xoom, hauv ob - ntawm lub laj thawj. Los ntawm sau cov kev pab cuam nyob rau hauv txoj kev uas lub laj thawj theem ntawm cov zis coj hloov hloov tsis tseg, koj yuav ua lub LED ntsais.
