Ua ntej kuv txawm pib ntawm qhov no, Kuv tsuas yog xav hais tias kuv paub tias qhov no tsis yog qee qhov poppin 'lub tswv yim tshiab uas tsis muaj leej twg xav txog ua ntej. Kuv paub qhov no yog cov lus qhia (zoo li kuv cov kua nplaum kub qhia) uas yuav kos ib pawg ntawm "Yog, txhua tus paub qhov ntawd," hom lus tawm tswv yim. Lub ntsiab lus ntawm cov lus qhia no yog tias kuv tsis tau xav txog nws ua ntej, thiab tej zaum nws yuav tsuas yog qhov kev txhawb siab rau lwm tus uas tsis tau hnov txog lub tswv yim no ua qee yam zoo nrog nws! Yog li, kuv tuaj nrog qhov no thaum kuv tau ua haujlwm ntawm ib qho ntawm kuv cov lus qhia yav dhau los txog kev nthuav koj cov LEDs nrog cov kua nplaum kub. Kuv tau pom RGB LEDs hauv is taws nem, thiab lawv zoo li zoo nkauj, tab sis kuv tsuas yog tshuab cov nyiaj ntawm ib feem rau txheej txheej tsom iav hmo kuv tau tsim, thiab kuv ua tsis tau (lub sijhawm) xav txog qhov tiag vim li cas thiaj yuav ib qho tshwj tsis yog "Kuv xav tau qee yam!" los yog "Lawv saib txias!" Zoo, Kuv tau zaum ib puag ncig blobbing kua nplaum rau ntawm LED, thiab qhov no tau los rau hauv siab. *** Hloov kho 5/3/10: Yog tias koj ua rau koj tus kheej tsis zoo txiv neej RGB LED thiab tshaj tawm qee cov duab (vam tias me ntsis zoo dua li kuv), Kuv mam xa ib daim tuaj rau koj! ***

Kauj Ruam 1: Qhov Koj Yuav Tsum Tau

Tsuas muaj rau ntu uas koj xav tau: 1 txhua qhov liab, ntsuab, thiab xiav 3mm LEDs, thiab 3 tus tiv thaiv. Koj tseem yuav xav tau qee cov kua nplaum kub (DAWB!?!?) Kuv siv lub khob cij ntawm kuv lub xov tooj cua radioshack kev kawm hauv chav kawm (kiag li qhov zoo tshaj plaws uas kuv tau pom thaum ua siab zoo). Kuv tau txais cov LED los ntawm qee qhov doodad lossis lwm qhov uas kuv tau khaws ntawm khw duas las. Kuv xav tias nws yog txhais tes uas koj tau npuaj teg thiab nws tau teeb lub LEDs. Cov resistors tuaj yeem sau los ntawm lwm yam ib yam nkaus, tab sis kuv muaj ntau yam pob uas kuv tau txais los ntawm radioshack.

Kauj Ruam 2: Xaiv Koj Cov Tiv Thaiv

Qhov no yog cov kauj ruam tsis zoo nkauj, thiab ib qho uas kuv tau ntsia rau qhov khoom kawg. Txij li thaum kuv tsis yog neeg Philistine, kuv yeej tsis ua tus tsav tsheb LED, Kuv ib txwm khiav lawv ncaj qha los ntawm roj teeb. Kuv npaj yuav siv qhov no nrog 9 volt, yog li kuv kaw lub LED ntawm kuv lub khob cij thiab txuas lawv mus rau 9v lub zog siv. Tom ntej no, Kuv sim cov LEDs nrog ntau yam kev tiv thaiv, sim ua kom lawv txhua yam kom zoo ib yam zoo ib yam ntawm 9 volts. Kuv xav tias kuv mus yuam kev hauv 2 qhov chaw ntawm no. Kuv yuav tsum tau muab cov LEDs los ze zog ua ke, txhawm rau txiav txim siab lawv qhov txheeb ze zoo dua qub. Kuv kuj yuav tsum tau pom tias kuv tau tso 1.2 volt roj teeb tso rau hauv lub lab, tsis yog 1.5 volt alkalines, yog li kuv tau sim lawv ntawm 7.2 volts, tsis yog 9. Nws tsis zoo, tab sis liab yog qhov muaj zog heev, thiab ntsuab ntsuab dhau lawm. Qhov kawg tiv thaiv qhov tseem ceeb uas kuv tau siv yog: Liab: 330 ohmsGreen: 1000 ohmsBlue: 2200 ohmsMaybe kuv tau muab nws sib xyaw thiab yuav tsum muaj liab thiab ntsuab lwm txoj hauv kev?

Kauj Ruam 3: Kaw cov LEDs

Txhawm rau muab cov LEDs ua ke, koj yooj yim npaj lawv hauv daim duab peb sab nrog txhua qhov tsis zoo coj mus rau hauv nruab nrab, thiab muab dab dab kub kua nplaum tso rau hauv nruab nrab. Tom qab ntawd tawv, quav cov ntawv ua rau me ntsis ntawm qhov chaw, thiab sib tw qhov tsis zoo ua ke. Kuv kis cov kua nplaum me ntsis ncig sab nraud kom paub tseeb tias nws yuav tuav ua ke. Tam sim no koj muaj RGB coj nrog 3 cathodes thiab ib qho anode! Koj tuaj yeem nres ntawm qhov no thiab hu nws ua tiav, lossis txuas ntxiv mus kuaj thiab ntxiv cov resistors.

Kauj Ruam 4: Kuaj thiab Ntxiv Cov Tiv Thaiv

Txij ntawm no mus, Kuv txuas lub LED rov qab rau hauv kuv chav kawm kev kawm, thiab sim nrog cov tshuaj tiv thaiv uas kuv tau xaiv ua ntej. Kuv yuav tsum tau nkees, lossis lwm qhov 9v tau ua qhov sib txawv thaum kuv txuas qhov ntawd, tab sis kuv tsis pom qhov teeb meem ntawm qhov no. Tom qab kuv tau txaus siab nrog qhov ci ntsa iab, Kuv tau muab cov resistors tso rau hauv qhov chaw, thiab nws tau ua tiav!

Kauj ruam 5: Xaus

Thaum kuv paub tias nws yuav yog lab lub sijhawm yooj yim dua thiab tsis yooj yim tsuas yog yuav ib qho ntawm cov no, Kuv tsis xav tias kuv tuaj yeem ua pov thawj tshuab cov nyiaj, thiab kuv kuj tsis xav tos thauj, raws li kuv tau tuaj nrog lub tswv yim rau kuv cov lus qhia tom ntej (yuav los sai sai!) thaum kuv tau xav txog yuav ua li cas.

Kuv xav tias nws ua haujlwm tau zoo heev, txawm hais tias yog kuv rov ua dua kuv yuav ceev faj ntau ntxiv txog cov neeg tawm tsam! Thov siv sijhawm me ntsis los tawm qhov ntsuas lossis tawm lus! Qhia rau kuv paub koj xav li cas, lossis yog tias koj tau ua qhov no ua ntej (raws li kuv paub tseeb tias muaj ntau) qhia kuv tias koj tau ua dab tsi nrog cov khoom kawg. Yog tias qhov no txhawb koj, tshaj tawm qee cov duab hauv cov lus thiab kuv yuav xa ib thaj rau koj!
