LED zaub yog ib lub vaj huam sib luag tiaj tus, uas yog tsim los ntawm ib qho me me LED module vaj huam sib luag. Nws cov qauv yog yooj yim heev. Cov editor hauv qab no yuav qhia koj txog kev qhia ntau lawm ntawm LED zaub.
Txhawm rau ua ib qho LED zaub, koj yuav tsum xub nkag siab txog cov khoom siv: lub rooj tsav xwm, lub hwj huam mov, daim npav tswj, thaiv, hloov fais fab mov thiab LED strip screen tswj daim npav.
Lub tsev board yog ib qho ntawm cov khoom tseem ceeb ntawm LED zaub, thiab qhov zoo ntawm chav tsev board ncaj qha cuam tshuam rau cov nyhuv zaub. Lub rooj tsavxwm yog tsim los ntawm LED module, tsav tsheb nti thiab PCB Circuit Board. LED module yog tiag tiag ua los ntawm ib tug loj tus naj npawb ntawm LED teeb-emitting ntsiab lus encapsulated nyob rau hauv ib tug matrix nrog resin los yog yas. Cov neeg tsav tsheb nti feem ntau yog 74HC595 74HC245 / 244 74HC138 4953. Cov khoom siv feem ntau siv rau cov ntxaij vab tshaus sab hauv tsev yog: tsis muaj: D=3.75; dot pitch 4.75mm 64 dots wide x 16 dots siab, 1/16 scanning sab hauv tsev brightness. Kev txhais ntawm ib leeg liab/liab thiab ntsuab ob-xim tsis: lub teeb txoj kab uas hla: hais txog txoj kab uas hla ntawm lub luminous qhov chaw D=3.75 hli qhov deb ntawm lub luminous qhov chaw yog 4.75 hli ---- Raws li qhov kev ncua deb ntawm tus soj ntsuam, lub kev xaiv ntawm qhov loj ntawm qhov dav dav hauv tsev 4.75 chav tsev board: 64x16 - feem ntau siv Cov module board yog qhov yooj yim mus yuav thiab pheej yig tshaj. 1/16 scan: hom tswj ntawm chav tsev board. Sab hauv tsev ci: hais txog qhov ci ntawm LED luminous point. Qhov ci ntsa iab sab hauv tsev yog tsim rau ib puag ncig uas xav tau fluorescent teeb pom kev zoo thaum nruab hnub. Xim: ib leeg liab, feem ntau siv thiab tus nqi pheej yig tshaj. Ob lub xim feem ntau xa mus rau liab thiab ntsuab, thiab tus nqi siab. Yog tias koj xav ua ib qho screen 128x16 dot, koj tsuas yog yuav tsum tau txuas ob lub rooj tsav xwm ua ke.
fais fab mov
Lub zog hluav taws xob feem ntau yog siv lub zog hloov pauv, 220V input thiab 5V DC tso zis. Nws yuav tsum tau taw qhia tias vim tias LED zaub yog cov khoom siv hluav taws xob muaj tseeb, nws siv lub zog hloov pauv thiab tsis tuaj yeem siv lub tshuab hloov pauv. Rau ib leeg liab sab hauv tsev 64x16 chav tsev board, tam sim no yog 2A thaum nws tag nrho teeb. Nws yog inferred tias thaum lub 128x16 dual-xim screen yog tag nrho lit, tam sim no yog 8A. Yuav tsum xaiv 5V10A hloov fais fab mov.
tswj daim npav
Nws raug nquahu kom siv tus nqi qis-zoo li daim npav tshuaj ntsuam xyuas los tswj 1/16 scan 256x16 dot dual-xim npo los sib sau ua ke tus nqi zoo tshaj plaws LED npo. Daim npav tswj hwm yog daim npav asynchronous, uas yog, daim npav tuaj yeem raug kaw kom txuag cov ntaub ntawv, thiab cov ntaub ntawv khaws cia hauv nws tuaj yeem tso tawm yam tsis tau txuas rau PC.
Thaum yuav ib lub rooj tsavxwm, thov nug txog cov kev txwv. 100% tshaj lub rooj tsavxwm muaj: 08 interface 4.75mm dot nrug 64 dot dav x 16 teev qhov siab, 1/16 scanning sab hauv tsev brightness. Ib leeg liab/liab thiab ntsuab 08 interface 7.62mm dot nrug 64 dots wide x 16 dots siab, 1/16 scanning sab hauv tsev brightness. Ib leeg-liab/liab-ntsuab dual-xim 08 interface 7.62 hli dot nrug 64 dots wide x 16 dots siab, 1/16 scan ib nrab sab nraum zoov brightness.
txuas
Muab faib ua cov ntaub ntawv kab, kab sib kis thiab kab hluav taws xob. Cov ntaub ntawv kab yog siv los txuas daim npav tswj thiab LED chav tsev board cable, thiab cov kab sib kis tau siv los txuas daim npav tswj rau lub computer. Cov hlua hluav taws xob yog siv los txuas cov khoom siv hluav taws xob thiab daim npav tswj hwm, cov khoom siv hluav taws xob thiab LED pawg thawj coj saib. Qhov txoj kab uas hla ntawm cov tub ntxhais tooj liab ntawm lub hwj huam qaum txuas nrog lub rooj tsavxwm yog tsis tsawg dua 1 millimeter (mm).
Accessories ntau lawm
Cable (cov ntaub ntawv cable) ntau lawm cable zoo ib yam li cov ntaub ntawv cable nyob rau hauv lub computer rooj plaub, tsuas yog hais tias qhov dav ntawm lub cable yog txawv me ntsis. Koj tuaj yeem yuav cov ntaub ntawv ntsig txog hauv Computer City. Txhawm rau ua cov cables, koj xav tau ib lub cuab yeej, uas yog ib hom tshwj xeeb ntawm pliers (daim duab), uas tuaj yeem txhim kho kev ua haujlwm zoo thiab tso tawm. Cov khoom siv los ua cov cables yog: cables, cable hau thiab cable caps. Nws yuav tsum raug sau tseg ntawm no tias yog tias koj ua 16PIN (16-xaim) cable, koj yuav tsum tau yuav ib lub 16PIN cable thiab sib xws loj cable taub hau thiab cables. Hauv cov kauj ruam ntau lawm, txiav cov xaim nrog ib khub txiab, thiab tom qab ntawd muab cov xaim kawg (ua tib zoo saib xyuas qhov sib npaug ntawm cov hlau thiab qhov kawg), tom qab ntawd muab tso rau hauv nruab nrab ntawm cov crimping pliers, nias ruaj khov, ces qhwv. xaim thiab nruab lub hau cable. Lub kaus mom cable tseem ceeb heev. Nws tuaj yeem tiv thaiv kab mob zoo thiab ua rau cov kab mob muaj zog tsis muaj kev txuag.
Lub hwj chim muab faib ua 220V fais fab qaum thiab 5V fais fab qaum. Lub 220V fais fab qaum yog siv los txuas lub zog hloov pauv mus rau lub hwj chim mov. Nws yog qhov zoo tshaj plaws los siv 3-pin plug, uas tuaj yeem yuav ntawm lub khw muag khoom kho vajtse. Ntawm no peb txhawj xeeb txog 5V DC fais fab qaum. Txij li thaum tam sim no ntawm 5V yog qhov loj, nws yog qhov zoo tshaj plaws los siv ib khub liab thiab dub (yuav tsum yog liab thiab dub) nrog ib tug tooj liab core txoj kab uas hla ntawm 1 hli los yog ntau dua. Yog tias ua tau, nws yog qhov zoo tshaj plaws los txuas cov hlau txuas mus rau ob qhov kawg ntawm cov kab ntau lawm.
RS232 kab tsim RS232 kab, siv los txuas lub computer thiab tswj daim npav, hloov kho cov ntaub ntawv tshuaj ntsuam. Ntawm no, koj yuav tsum siv DB9 connector thiab network cable (muaj nyob rau hauv Computer City). Ua tib zoo saib ntawm lub taub hau ntawm DB9, muaj cov lej ntawm nws, txuas 5 rau xim av thiab 3 rau xim av. Clamp lub cable thiab nruab rau hauv lub taub hau DB9. (Nws tseem ceeb heev ntawm no, nco ntsoov clamp nws, rub nws ob peb zaug, thiab tom qab ntawd saib seb nws puas poob). Tom qab ntawd ntsuas ob qhov kawg nrog lub multimeter thiab tig rau. Nws yuav tsum tau taw qhia ntawm no tias lub taub hau ntawm DB9 muab faib ua txiv neej thiab poj niam. Lub nraub qaum ntawm lub computer belongs rau lub qhov (socket) poj niam, yog li koj yuav tsum tau yuav lub ntsaws. Yog tias koj tsis ua' tsis nkag siab, thov xyuas koj lub PC kom zoo. Niaj hnub no lub laptops feem ntau tsis muaj qhov chaw nres nkoj serial. Thov muas USB rau RS232 serial chaw nres nkoj.
