Hloov kho: Thaum kuv tshaj tawm cov lus qhia no ntau xyoo dhau los, LEDs tau kim dua me ntsis li niaj hnub no. Yog tias koj pom koj tus kheej nrog teeb tsa teeb Christmas, qhov no yuav yog txoj hauv kev zoo los cawm lawv. Nrog tus nqi tam sim no ntawm LEDs, tsuas yog vim li cas kuv thiaj xav kom rub cov teeb tshiab los ua kom noj qab nyob zoo yog tias koj nyiam/xav tau cov duab ntawm cov diffusors rau lub hom phiaj zoo nkauj. Ib txoj hauv kev zoo tshaj los yuav LEDs (IMHO) yog Ebay. Yog tias koj mus nrog tus muag khoom thoob ntiaj teb, tsuas yog paub tias nws yuav siv sijhawm ib hlis kom tau txais koj li LEDs los ntawm kev cai. Los ntsej muag nws, cov khoom siv hluav taws xob tsis pheej yig. Ua tau zoo, siab ci LEDs yog kim thiab nyuaj nrhiav chaw feem ntau.

Kuv muaj kev daws teeb meem. Yuav ua li cas txog cov LEDs zoo uas tsuas yog nqi 6 xees ib thooj tshiab?

Tos kom txog thaum tom qab Christmas thiab foob pob koj lub khw kho vajtse hauv cheeb tsam rau lawv "tom qab-Christmas tshem tawm" muag. Koj tuaj yeem pom cov hlua thiab cov hlua ntawm LED Christmas teeb rau 75% tawm ib txwm, uas txhais tau tias koj siv li $ 3 rau 50 LEDs. Qhov ntawd txuag koj li $ 22.5 yog tias koj yuav yuav cov LED zoo ib yam ntawm cov khw muag khoom online. Koj cov LEDs raug nqi koj 13% ntawm qhov lawv xav tau ua ntej. 6 xees rau kuv li vs $ 1.50 khw muag khoom.

Kuv nyiam ua yam pom kev, nco ntsoov saib tag nrho cov duab thiab cov duab sau tseg rau hauv cov lus tob thiab cov lus qhia kom ua rau koj lub neej yooj yim dua thiab cov lus qhia no zoo dua!

Kauj ruam 1: Cov ntaub ntawv

Yog lawm, qhov no yog yam koj yuav xav tau: Cov khoom siv: -LED teeb Christmas -Cov kab xev hluav taws xob -Lub zog siv hluav taws xob -2 cov nyiaj npib loj Cuab Yeej: -Wire strippers -Scissors -Time, ntau lub sijhawm ……

Kauj Ruam 2: Npaj Txoj Haujlwm

Tshem cov hlua tawm ntawm lub thawv. Yog tias koj teeb lub chord thiab saib ze, koj yuav pom ob peb LEDs nrog peb lub xov hlau tawm. Vim tias LED tsuas tuaj yeem siv hluav taws xob khiav ib qho kev qhia, thiab AC tam sim no (qhov koj lub qhov hluav taws xob tso tawm) khiav hauv ob txoj kev qhia. Ob ntawm cov xov hlau ntawm LED tau txuas ncaj qha raws li kom tso cov dej ntws rov qab los ntawm lwm txheej ntawm LEDs thiab tso cai rau LEDs ua haujlwm. Cov LEDs no tsis tso cai rau peb tshem tawm cov LED los ntawm qhov seem ntawm txoj hlua yooj yim heev, yog li peb yuav tsum txiav tawm lub qhov hluav taws xob/ntsaws nrog rau 3 xaim LEDs. Teeb lawv ib leeg, peb tuaj yeem siv lawv tom qab.

Kauj ruam 3: Unravel lub Strand

Qhov no zoo li nws tus kheej piav qhia, tab sis cia kuv muab koj ob peb yim pab: -Unravel ib leeg LED txoj hlua los ntawm ob lub zog txuas -nws ua rau tsawg dua tangles -Koj huv si … nras thiab khi cov hlua LED thaum koj mus, kuj ua rau tsawg dua tangles -Tsis txhob rub, sib cais cov hlua … ib zaug ntxiv, qhov no yuav ua rau kom tsis muaj kev cuam tshuam ntau ntxiv thiab pob qij txha Koj yuav mus txog lwm ob lossis peb 3 -xaim LED txoj hauv kev, yog li khaws cov xaim hluav taws xob tshem tawm/txiav tawm.

Kauj Ruam 4: Txiav thiab Sawb

Txhawm rau ua kom tiav cov khoom lag luam zoo, koj yuav tsum txiav kom ze rau nruab nrab ntawm LED's li koj tuaj yeem ua tau. Nws yuav ntse los tso qee qhov ntawm LEDs hauv 3 lossis 4 qhov xwm txheej uas koj xav tau lawv rau qhov haujlwm tom ntej li ntawd - nws txuag lub sijhawm los ntawm kev tsis tas yuav siv cov hlua sib txuas ua ke ntawm cov teeb. Tom qab koj tau txais tag nrho cov LEDs sib cais, koj yuav tsum tau hle cov hlua tawm ntawm cov xov hlau. Txoj cai zoo ntawm tus ntiv tes xoo yog tshem tawm ib nrab ntawm txoj kab uas hla (piv txwv li lub vojvoog) ntawm ib npib. Qhov no yuav ua rau koj muaj chaw txaus ntxiv rau kev sib tw, sib dhos, lossis qhov koj yuav ua rau cov xov hlau. Yog tias koj npaj yuav siv cov no rau ntawm lub khob cij, koj yuav xav kom tshem tawm tsawg dua (saib cov kauj ruam tom ntej) lossis cov laug ntawm cov khoom tseem ceeb 22 GA xaim.

Kauj ruam 5: Ua Twist

Tsis yog, tsis yog kev seev cev. Txhawm rau khaws cov khoom kom huv thiab siv, peb yuav tsum tau ntswj qhov kawg. Qhov no tseem yuav ua kom yooj yim siv nrog cov laug cam ib yam nkaus, txawm hais tias koj yuav xav txiav lawv luv dua kom yooj yim dua.

Kauj Ruam 6: Kuaj Cov Thawj Coj

LED sawv rau Lub Teeb Emitting Diode. Lub diode yog cov khoom siv hluav taws xob uas tso cai rau hluav taws xob ntws hauv ib qho, thiab tsuas yog ib qho kev qhia. Raws li qhov tshwm sim, LEDs tsuas yog ua haujlwm thaum hluav taws xob ntws mus rau qhov tshwj xeeb. Cov kauj ruam no yuav pab koj sau koj cov LEDs kom koj paub txoj hauv kev twg los siv koj li LEDs hauv cov phiaj xwm yav tom ntej thiab txuag koj lub sijhawm. Kuv siv kuv Arduino Mega pub los ntawm phab ntsa-wart ua lub zog siv. Nrog kuv cov LED tshwj xeeb, Kuv tsis tas yuav siv cov tshuaj tiv thaiv nrog kuv lub zog siv, tab sis koj yuav tsum siv cov tshuaj tiv thaiv nruab nrab ntawm koj li VCC thiab koj cov LED. Txhawm rau ntsuas LEDs yooj yim dua thiab nrawm dua, Kuv tau qhwv thiab kaw cov xov hlau nyob ib puag ncig ob lub tebchaws Asmeskas (ib qho nyiaj npib loj yuav ua) muab rau kuv cov ntsiab lus sib cuag loj dua. Ib ntawm cov xov hlau tau sau nrog lub me me ntawm kab xev hluav taws xob los qhia tias nws yog VCC thiab lwm qhov yog hauv av. Koj yuav tsum tau ntsuas txhua qhov LED thiab muab ib daim me me ntawm daim kab xev dawb tso rau ib puag ncig ntawm cov hlau lead zoo.

Kauj Ruam 7: Ua tiav Cov Khoom Siv Demo Video (Ci iab!)

Zoo, ntawm no yog qhov ua piv txwv ntawm LEDs hauv kev ua ntawm kuv Arduino Mega micro maub los. Tsis muaj dab tsi zoo nkauj heev - Kuv nyuam qhuav ua tiav tso lub thawv rau tag kis no. Nov yog qhov kev kos duab kos kom ntseeg tau tias txhua yam ua haujlwm tau zoo.. Txaus siab rau!
