Cov lus qhia no qhia yuav ua li cas xaim ib lossis ntau lub LEDs hauv ib qho yooj yim thiab meej. Tsis tau ua dua ib txoj haujlwm twg ua ntej nrog LEDs thiab tsis paub siv lawv li cas? Nws zoo, tsis muaj kuv.
*** Yog tias koj tau xaim LEDs ua ntej, qhov kev piav qhia no yuav zoo li yooj yim dhau. Xav txog koj tus kheej ceeb toom. ***
Kauj Ruam 1: Tau Qee Cov LEDs
Yog li kuv tsis tau ua ncaj ncees - Kuv tau siv LEDs ib zaug lossis ob zaug ua ntej rau cov ntawv thov yooj yim, tab sis kuv yeej tsis tau paub tiag tias kuv tau ua dab tsi, thiab txij li muaj ntau txoj haujlwm ntawm kev qhia siv LEDs, Kuv xav tias kuv yuav zoo ib yam qhia kuv tus kheej thiab tshaj tawm txog nws ib yam Kuv paub tias muaj ntau txoj haujlwm tau tshaj tawm uas muaj cov ntaub ntawv hais txog yuav ua li cas xaim LEDs rau cov phiaj xwm yooj yim - LED Throwies, LED Pib Ua Haujlwm: Tshooj 2 thiab 9v LED teeb nyem - teh zoo tshaj evarrr !, tab sis kuv xav tias muaj tseem yog qee qhov siv rau cov ncauj lus ntxaws los ntawm kev piav qhia ntxaws txog cov hauv paus ntawm LEDs rau txhua tus neeg uas tuaj yeem siv nws. Txog qhov haujlwm no kuv tau mus rau Radioshack vim tias nws ze thiab muaj coob tus neeg tau nkag mus rau nws - tab sis ceeb toom lawv cov nqi yog qhov siab heev rau cov khoom zoo li no thiab muaj txhua yam ntawm qhov chaw qis tus nqi mus yuav LEDs online. Txhawm rau teeb lub LED koj xav tau ntawm qhov tsawg kawg nkaus ntawm LED nws tus kheej thiab lub zog siv. Los ntawm qhov kuv tau nyeem los ntawm lwm cov lus qhia hauv xov hlau LED hauv lub resistor yuav luag ib txwm yog lub tswv yim zoo. thiab rub tawm txhua yam uas tsis ntau dua $ 1 lossis $ 2 rau ib qho LED. Kuv tau txais: 2760307 5mm Liab LED 1.7 V2760351 5MM Daj LED 2.1 V2760036 Flasher Liab LED 5 V2760041 2 Pob Liab LED 2.6 V2760086 Jumbo Liab LED 2.4V Lub Hwj Huam - Kuv yeej tsis paub tias kuv yuav xav tau hwj chim li cas yog li kuv yuav qee 9V roj teeb thiab qee qhov 1.5V AA's. Kuv xam tias yuav tso cai rau kuv sib xyaw thiab sib xyaw thiab ua kom muaj qhov sib txawv ntawm qhov sib txawv kom ua rau qee yam teeb pom kev - lossis tsawg kawg hlawv cov me me nqus tawm hauv cov pa luam yeeb yas tsw tsw ntxhiab. Resistors - Ib zaug ntxiv, Kuv tsis paub tseeb tias kuv yuav xav tau ntawm cov resistors ntawm no ib yam nkaus. Txij li thaum kuv tau txais tag nrho cov pawg sib txawv ntawm LEDs nrog ntau qhov hluav taws xob Kuv paub tias kuv yuav xav tau ob peb yam sib txawv ntawm cov tiv thaiv, yog li kuv tsuas yog yuav ntau yam pob ntawm 1/2 Watt Carbon Film Resistors (2710306). Kuv tau sau cov phom phom, cov laug, rab koob lub qhov ntswg, cov cuab yeej hluav taws xob, qee qhov xov hlau tseem ceeb thiab kab xev hluav taws xob ib yam vim kuv xav tias lawv yuav muaj txiaj ntsig.
