Tswj cov xim ntawm lub teeb ci muaj zog LED nrog lub chaw taws teeb tswj, khaws cov xim thiab rov nco lawv ntawm qhov xav tau. Nrog qhov no kuv tuaj yeem tswj cov xim ntawm lub teeb ci rau ntau yam xim sib txawv siv peb lub hauv paus xim: ntsuab ntsuab thiab xiav. Ntxiv lawv toghether nrog kev siv sib txawv tuaj yeem yeld zoo heev ntawm cov xim los ntawm qhov pom pom qhov tshwj xeeb Kuv lub teeb pom kev zoo tuaj yeem hloov xim los ntawm 32 qhov ntsuas qhov tseem ceeb rau txhua RGB xim muab 32*32*32 = 32768 sib txawv ua ke ntawm cov hue, siv thiab ci. Nws tseem tuaj yeem khaws 10 qhov sib txawv ua ke tuaj yeem qhib lossis tua tawm, txhua qhov no los ntawm TV tswj chaw taws teeb. Qhov kev siv ntawm txhua qhov liab, ntsuab thiab xiav yog ua tiav ntawm PWM yog li cov cua sov tau tawg mus rau qhov tsawg kawg nkaus. thiab tsis muaj lub pob nyem raws li kev tswj tau ua tiav los ntawm kev tswj chaw taws teeb. Kuv siv lub voj voog no los teeb lub paj paj. Cov ntaub ntawv tiaj tus ntawm lub thawv kuv tau xaiv ua haujlwm zoo ntawm kev sib npaug ntawm lub vase. Qhov duab muab qee cov tswv yim. Ib hnub kuv muaj peev xwm yuav ib qho ntawm cov iav ntsuas nrog LASER tsim 3D duab sab hauv mus nrog lub teeb. Rau tam sim no iav vases tsuas yog zoo. UAB TSEEB: Kuv upload V1.1 qhov twg ntawm lub zog nce lub micro tso tawm qhov txiaj ntsig los ntawm tus lej cim 0. Tsuas yog xyuas kom tseeb tias koj khaws koj lub hwj chim ua xim hauv lub cim xeeb 0 thiab ntawm lub zog nws yuav tshwm sim. Yog tias koj xav tau mus rau lub teeb tawm, tsuas yog khaws txhua qhov khoob hauv cim lej 0. CiaoHey Kuv nyob ntawm qhov zoo tshaj plaws ntawm Phau Ntawv Qhia!

Kauj ruam 1: Kev piav qhia

LED kuv xaiv yog Seoul Semiconductors ib leeg nti. Nws kim heev, tab sis nws muaj zog muab lub teeb ci heev. Nws tseem muab cov xim sib xyaw zoo heev. Nws tuaj yeem hloov los ntawm qhov pheej yig dua thiab tej zaum zoo ib yam; thaum kuv tsim qhov no, nws tsuas yog qhov tsim nyog uas kuv tuaj yeem pom. Ua rau LED qhov ntsuas lub zog siab nws yog qhov tsim nyog kiag li los muab nws nrog cov cua sov tsim nyog zoo ib yam li koj pom hauv cov duab; ua ntej tso lub Circuit Court ua tiav hauv rooj plaub tshawb xyuas cov LEDs rau cua sov ntawm qhov siab tshaj plaws ntawm txhua ntawm peb xim. Tam sim no txwv cov resistors Kuv xaiv phim kuv LED nkaus xwb! Kuv tau xaiv 10% tsawg dua li qhov pom zoo VI qhov tseem ceeb ntawm cov ntawv nkhaus. Cov txheej txheem kev tawm sab nraud tuaj yeem ua rau muaj kev nyab xeeb los rub cov LEDs tam sim no ua kom muaj lub zog zoo dua. Qhov LEDs sib txawv muaj qhov sib txawv. Txheeb xyuas cov ntawv teev tseg rau qhov siab tshaj plaws thiab cov lus pom zoo rau koj LED. Kuv yuav kuv cov LED online ntawm Distrelec. Farnellinone nqa nrog lawv. Qhov tsav tsheb tau tshaj NPN transistors dhau qhov ntsuas rau qhov xav tau tam sim no. Tsawg zog TO126 kaw NPNs yuav tsum ua kom zoo. Raws li Transistor tau tsav nrog PWM, lawv cov kev tso tawm mus rau qhov tsawg kawg yog li cov cua sov tsis tsim nyog. Tus neeg txais khoom muaj lub vijtsam xim hlau uas yuav tsum tau muab tsau rau 0V. Qee qhov me me me me yog los ntawm Temic thiab tuaj yeem yuav los ntawm tib qhov chaw saum toj no. Xyaum txhua tus txais tau ua haujlwm tau zoo, muab tias nws muaj 5Volt logic qib (thiab khoom siv) thiab muaj tib yam (lossis kaw) cov zaus ntau dua li cov chaw taws teeb xa khoom (feem ntau 38-50kHz). Thaum rhuav tshem TV lossis lwm yam khoom siv hauv chaw taws teeb, txoj cai zoo yog kom txuag tau ob qho chaw deb thiab tus txais. Los ntawm txoj kev, Kuv nyiam txuag kev hloov pauv, VFD, lub cev muaj zog ib yam, tab sis qhov ntawd yog lwm zaj dab neeg. Qhov teeb no siv European tus qauv RC5 rau Philips TV remotes; Txhua lub programmable tswj chaw taws teeb uas txhawb nqa Philips TVs yuav tsum yog qhov zoo, kuv tau sim ib qho thiab nws ua haujlwm tau. Ob qho kev txiav txim siab tej thaj chaw deb thiab PWM tsim cov txheej txheem yuav tsum nkag siab los ntawm qhov chaws kuv tau hais tawm. Circuit yuav tsum tau muab los ntawm 5 Volt, 1A qhov chaw zoo. Thaum xub thawj kuv tau siv kab hluav taws xob tswj hluav taws xob IC ntawm lub rooj tsavxwm rau hauv rooj plaub, tab sis cov cua sov uas tsim los ntawm tus tswj hwm yog txoj hauv kev ntau dhau kom yooj yim dhau los ntawm hauv lub npov, yog li kuv tau tshem nws thiab tam sim no kuv tab tom siv cov khoom siv sab nraud nrog tswj 5V 3A cov zis. Cov LEDs tau siv ncaj qha los ntawm 5Volt, yog li txhua qhov kev hloov pauv yuav pov tseg koj cov lus teb meej rau cov dej ntws ntws los ntawm LEDs, tej zaum yuav ua rau lawv puas tsuaj. Yog li, qhov zoo dua thiab ruaj khov cov khoom siv, zoo dua. Qhov ntaub ntawv kuv tau xaiv yog Teko TB9, nws zoo li ntxim nyiam rau kuv thiab cov khoom pob tshab me me tuaj yeem tso rau saum rooj plaub+LED yam tsis muaj kev pheej hmoo poob.

Kauj ruam 2: Kev ua haujlwm

Cov chaw taws teeb tswj txhua txoj haujlwm RGB teeb.

Cov chaw taws teeb tswj cov nyees khawm 1, 2 thiab 3 rub R, G thiab B siv zog, cov nyees khawm 4, 5 thiab 6 rub qhov sib zog; Channel nce thiab channel nqis khawm shuffle los ntawm 10 khaws cia qhov tseem ceeb ntawm R G & B siv. Koj tuaj yeem nkag mus ncaj qha qhov ua ntej nrog khawm 'ntim+' ua raws los ntawm tus lej ua ntej (0 txog 9). Koj tuaj yeem khaws koj cov xim nyiam nias 'ntim-' ua raws los ntawm tus lej ua ntej (0 txog 9). Lub hwj chim rau/tawm khawm ua raws nraim qhov koj xav tau: nws qhib thiab tua lub teeb.

Kauj Ruam 3: Kev tsim kho

Kuv tsim PCB rau lub Circuit Court tab sis tsis siv nws. Kuv siv perfboard hloov pauv. Qhov duab yuav tsum muab cov ntaub ntawv txaus rau txhua tus neeg txaus siab ua raws nraim qhov kuv tau ua. Nyob ntawm qhov siab ntawm lub npov uas koj xaiv, lub xwm fab yuav tsis tsim nyog ntxiv. Nco ntsoov lub tshav kub tsim los ntawm LED. Tsis tas li yog tias koj tab tom npaj yuav siv qhov no kom pom lub iav iav los ntawm hauv qab no, tom kawg yuav tiv thaiv kom tsis txhob tshav kub. Use 5Volt tswj cov phab ntsa adapter 1.5A. Thaum siv thawj zaug, saib xyuas cov cua sov tsim tawm vim nws nyob ntawm ntau ib puag ncig (rooj plaub yas, rwb thaiv tsev kub, khoom ntawm LED). Lub teeb muaj zog thiab mloog zoo. Qhov microprocessor yuav tsum tau ua haujlwm. Kuv siv WinPIC. Lub khoos phis tawj sib txuas yog qhov tau piav qhia ntawm no. Qhov txuas koj tuaj yeem pom cov lej, PCB (txheeb xyuas qhov no ua ntej, raws li kuv tsis tau siv nws!), Cov lej cim tau hais tawm tag nrho thiab HEX cov ntaub ntawv kom hlawv ncaj qha rau hauv PIC. Lub software tau tsim nrog MPLAB los ntawm Microchip. Hope koj txaus siab rau cov lus qhia no. Yog tias koj ua koj tus kheej lub teeb, thov qhia cov duab ntawm koj tsim thiab thov tawm lus tawm tswv yim. Ciao5V.
