Kuv nyiam txhua hom LED strips. Kuv ua lub teeb zaj sawv zoo nrog lawv. Txawm tias cov uas tsis tuaj yeem hais qhia tau muaj txiaj ntsig. Kuv tau ua lub teeb ci kev lag luam sab nraum zoov lub teeb los ntawm kev txuas lawv mus rau qhov tsis muaj kab tav tav li ntawd thaum kuv tsob ntoo kauv tawg tawm kuv txiav txim siab qhwv qhov ntev ntawm cov coj coj los puag ncig nws.

Kauj ruam 1: Tswj

Kuv txiav txim siab siv cov leds RGB tsis tuaj yeem hais txog. Qhov no txhais tau tias kuv tuaj yeem muaj cov txheej txheem ua haujlwm tab sis txhua lub leds hloov xim ib txhij. Qhov no kuj txhais tau tias xav tau tus tswj hwm. Kuv tuaj yeem tau siv ib qho arduino uno thiab tau ua thawj qhov kev sim siv daim thaiv npog RGB tab sis xaus nrog kev siv ib lub rooj tsav xwm kev cai nrog liab qab Atmega328 nti. Tsuas yog yuav tsum tau hloov lub phiaj xwm phiaj xwm thiab ua haujlwm ncaj qha.

Kuv muaj cov laug cam no tshuav los ntawm lwm cov phiaj xwm teeb. Xav tias dawb los siv tus nqi pheej yig inline preprogrammed maub los zoo li kuv tau ua ntawm kuv lub kaus xwb.

Kuv tau xaus siv qhov kev sib tw qeeb crossfade ua lub hauv paus rau tsob ntoo.

Thawj lub xim tau teeb rau dub (yog li thawj xim ploj mus) hauv), tab sis * koj tuaj yeem teeb tsa thawj xim kom muaj lwm yam xim * 2. Lub voj sab hauv ua haujlwm rau 1020 kev npaj; qhov 'tos' sib txawv * teeb tsa lub sijhawm kwv yees ntawm kev hla ib leeg. Hauv kev xav, * a 'tos' ntawm 10 ms yuav tsum ua kom hla ntawm ~ 10 vib nas this. Hauv * kev coj ua, lwm txoj haujlwm cov cai tau ua qhov qeeb no * nqis mus ~ 11 vib nas this ntawm kuv lub rooj tsavxwm. YMMV. * 3. Yog tias 'rov ua dua' tau teeb tsa rau 0, qhov kev zov me nyuam yuav voj mus tas li. * yog tias nws tau teeb tsa tus lej, nws yuav rov ua cov lej ntawd, * tom qab ntawd nres ntawm cov xim kawg hauv ntu.

Kauj ruam 2: Muab tsob ntoo

Kuv siv cov dej tsis thwj vim cov no yuav nyob sab nraum zoov. Lawv tau lo ntawm lawv tus kheej tab sis kuv tau nrawm nrog cov xov hlau txuas kom ntseeg tau tias lawv nyob twj ywm. Yooj yim thiab yooj yim hack. Kev muaj peev xwm ua kom muaj zog ntawm kab txaij ua rau nws yooj yim los pub lub zog tso rau hauv qab thiab tau txais lub zog tawm sab saum toj mus rau lub hnub qub.

Kauj Ruam 3: Tsis Txhob hnov qab Lub Hnub Qub nyob saum

Rau lub hnub qub Kuv tau siv ib khub ntawm 10W chips kom tau txais kev saib xyuas. Kuv muab lawv tso rau ntawm daim ntawv tooj liab ua lub rhaub dej kub. Kuv tuaj yeem siv daim kab xev ntau dua vim tias tshuav me ntsis.

Kauj ruam 4: Sim Nws Tawm

Thawj zaug tau ua kom nrawm nrawm dhau….

Thaum kuv calmed nws cia nws saib zoo nkauj heev.
