Tsis ntev los no, nws tau dhau los ua qauv zoo los nrhiav ntau yam kev daws teeb meem siv cov hlua LED. Lawv muaj ntau yam sib txawv, thiab ib qho ntawm lawv yog "khiav lub teeb" LED sawb. Nws tau txais koob meej vim tias nws tuaj yeem siv los ua kom yooj yim ua tiav yam tsis muaj kev sib tw thiab teeb pom kev zoo.
Peculiarities
"Tua hluav taws", lossis, raws li nws tseem hu ua, SPI chaw nyob daim kab xev yog ntau yam khoom siv tsim los tsim teeb pom kev zoo sab hauv. Qhov tshwj xeeb ntawm cov teeb pom kev zoo rov qab yog tias muaj lub sijhawm tshwj xeeb los tswj txhua LED ntawm lub rooj tsavxwm cais . Vim li no, daim kab xev qee zaum kuj tseem hu ua "nthwv dej taug kev".
Nws yog qhov tseem ceeb uas cov kab txaij muaj qhov ntev sib txawv nyob ntawm qhov ntev ntawm cov chaw uas yuav tsum tau kho.
Dhau li, cov xim ntawm LEDs kuj tuaj yeem ua raws kom haum rau tus kheej cov kev xav tau . Lub ci ci tuaj yeem hloov kho. Koj tsis tas yuav txhawj xeeb txog yuav kho lub diode strip li cas, vim nws yog nws tus kheej-nplaum.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm
Txhawm rau nkag siab ntxaws cov ntsiab cai ntawm kev ua haujlwm ntawm "tua hluav taws" daim kab xev, koj yuav tsum nkag siab tias kev siv kab txaij LED zoo li cas. Lub diodes ntawm daim kab xev txheem ci tib yam raws nws qhov ntev tag nrho. SPI daim kab xev tau nruab nrog tus tswj tshwj xeeb, nrog kev koom nrog uas qhov ci thiab lub teeb siv tau raug tswj . Cov maub los tuaj yeem nruab nrog cov chaw taws teeb tswj.
Diodes ua haujlwm ntawm tib lub Circuit Court hu ua pixels . Yog tias lub cuab yeej muaj qhov hluav taws xob ntawm 12 volts, tom qab ntawd muaj 3 diodes ib pixel. Tab sis kuj tseem muaj kab xev uas txhua diode muaj kev tswj cais.
Yuav tsum muaj dab tsi?
Koj tuaj yeem sim ua cov hlua LED nrog koj txhais tes, muaj qee qhov kev paub txog physics. Txhawm rau ua daim kab xev, koj yuav tsum npaj cov ntaub ntawv hauv qab no:
- strips ntawm PCB (zoo dua yog tias nws yog ntawv ci);
- LEDs nrog kev ua haujlwm siab txog li 3 volts;
- resistors - cov cuab yeej tshwj xeeb, txoj haujlwm uas yog txhawm rau txwv qhov ntws tam sim no los ntawm diodes;
- cua sov ntsws raj;
- xov hlau (cov kws tshaj lij paub tseeb tias koj tuaj yeem siv yuav luag txhua ntu);
- Scotch;
RGB maub los
Ntxiv rau txhua qhov saum toj no, nws yog qhov tsim nyog los npaj cov kab uas ua los ntawm cov fwj yas.
Lawv tsim nyog kom diodes hloov lawv cov xim thaum ua haujlwm ntawm lub cuab yeej.
Los ntawm cov cuab yeej koj yuav tsum npaj:
- laum;
- soldering hlau;
- txiab;
- ntsia hlau;
- siv tshuab ziab khaub ncaws.
Qhov tom kawg tuaj yeem hloov pauv nrog lub teeb pom kev zoo ib yam, nws yuav tsum tau ua kom sov lub raj cua sov.
Tsim kev xaiv
Nyob rau theem pib ntawm kev ua haujlwm, nws yog qhov tsim nyog los tsim daim duab ntawm kev teeb tsa ntawm diodes thiab resistors. Cov ntsiab lus yuav tsum tau muab sib dhos ua ntu ntu. Thiab qhov xav tau kev tiv thaiv tuaj yeem suav tau yooj yim los ntawm kev ua raws li kev paub Ohm txoj cai. Tom ntej no, koj yuav tsum txiav txim siab seb cov hlua LED yuav yog dab tsi . Qhov kev xaiv yooj yim tshaj plaws yog xav tau ib leeg-kab.
Ib txoj kab
Kev tsim khoom ntawm txawm tias qhov yooj yim tshaj plaws ntawm cov hlua LED tau ua tiav hauv ntau theem:
- nws yog qhov tsim nyog los txiav ib daim hlab los ntawm daim ntawv - cov no yuav yog qhov seem;
- tom qab ntawd koj yuav tsum tau laum lossis ua qhov hauv lawv nrog awl (txij li tau tsim daim kab xev RGB, cov LEDs yuav tsum tau hloov pauv xim);
- nws yog ib qho tsim nyog yuav tau muab cov khoom npaj tso rau hauv lub qhov raws li daim duab;
- tom qab ntawd cov xov hlau tau muab siv los muab hluav taws xob;
- kom pom qhov ntxim nyiam, daim kab xev yuav tsum muab tso rau hauv lub raj cua sov.
Cov cua sov yuav tsum tau ua kom sov nrog cov tshuab ua kom plaub hau los yog lub teeb sib zog; nyob rau hauv qhov cuam tshuam ntawm qhov kub thiab txias, nws yuav nqaim thiab ua kom nruj rau cov khoom.
Ob txoj kev
Yog tias cov phiaj xwm yuav ua ob txoj kab khoom, tom qab ntawd lub hauv paus ntsiab lus ntawm nws kev tsim khoom yuav tsis muaj qhov sib txawv los ntawm ib qho dhau los. Qhov tshwj xeeb yuav yog qhov sib txuas sib txuas ntawm cov kab txaij rau lub zog siv.
