Kauj Ruam 1: Tsim Circuit Court
Kuv tsim lub Circuit Court los siv cov kab txaij ob qho tib si ua lub thauj tog rau nkoj rau LEDs thiab ua ib qho kev sib txuas tsis zoo, yog li txhua tus LED muaj ib txhais tes txuas rau lub rooj tsavxwm, thiab lwm qhov poking los ntawm, thiab txuas nrog - ntawm tus tiv thaiv - rau qhov zoo ntawm lub roj teeb. Qhov daim duab xav tau qee qhov kev piav qhia, thiab tsim ib feem ntawm cov lej. Nws yuav tsum pom tseeb tias txhua lub voj voog sawv cev rau ib qho LED, thiab txhua lub xwmfab loj yog qhov zoo. 1. Siv lub laum los yog bradawl, tshem cov tooj liab nyob ib ncig ntawm lub qhov cim nrog tus ntoo khaub lig. Cov no yuav yog qhov twg txhua qhov zoo (qhia los ntawm txhais ceg ntev me ntsis ntawm ib sab yam tsis tiaj tus) ceg yuav hla mus, thiab yog li nws yog qhov tseem ceeb uas lawv tsis ua hluav taws xob sib cuag nrog lub rooj tsavxwm. 2. (Nco tseg ua ntej pib theem no: lub hauv paus LED xav tau kev kho tshwj xeeb, yog li thov nyeem ua ntej tso rau nws). Xaiv txhua lub LED tig. thawb ob txhais ceg zoo thiab tsis zoo los ntawm. Cov ceg tsis zoo yuav tsum tau muab muag rau lub rooj tsavxwm, tab sis rau cov LEDs hauv daim duab uas muaj kab txuas los ntawm lawv, cov no yog qhov uas ob txhais ceg yuav tsum tau khoov thiab ntov kom ntev kom lawv rov nkag tau rau hauv lub rooj tsavxwm ntawm sab nraub qaum. koom nrog txhua qhov 'tsis zoo' ua ke. Txoj hauv kev yooj yim tshaj plaws los ua qhov no yog txhawm rau txhua tus LED los ntawm sab laug mus rau sab xis, ua ntej kom ruaj nws cov ceg tsis zoo nrog cov laug, thiab tom qab ntawd tsuas yog txiav ceg tsis zoo uas tsis xav tau txuas ntxiv (ntawm uas muaj kaum ib). tshwm hauv qhov chaw, nws yuav tsim nyog kom 'kis' ob txhais ceg ua ntej tso nws, khoov lawv tawm thiab thim rov qab kom lub hauv paus ntawm LED hla nruab nrab qhov. Qhov no tuaj yeem txhais tau tias nws sawv los sawv me ntsis 'txaus siab' ntawm lub rooj tsavxwm, thiab rau qhov yooj yim koj yuav xav tshem nws qhov no yuav ua rau pom tseeb ntawm hav zoov ntawm txhais ceg, tab sis nws yuav tamed! Tej zaum koj yuav xav ua qhov khoov ntawm ob txhais ceg kom coj qhov "tsis zoo" thoob plaws lub rooj tsavxwm tam sim no, lossis tos kom txog qib tom ntej. Qhov lwm sab ntawm pawg thawj coj saib yuav pom zoo dua (saib daim duab thib ob hauv cov kauj ruam no).
Kauj Ruam 2: Ua kom zoo ob txhais ceg thiab ua ntawv thov cov neeg tawm tsam
Cov theem tom ntej yog siv cov nplaum rau cov ceg zoo, muab cov insulating sib koom ua ke uas yuav tiv thaiv nws los ntawm kev luv mus rau cov kab uas nyob ib sab thaum ob txhais ceg tau khoov. Yog tias siv daim nplaum ob-ntu, muaj txoj hauv kev zoo nws yuav tau pib kho los ntawm lub sijhawm koj nyob ib nrab ntawm, uas ua rau daim ntawv thov tsis yooj yim, yog li nws yuav yog qhov zoo siv ob pawg me me ntau dua li ib qho loj. qhov kawg yuav tsum tshwm zoo li thawj daim duab hauv qab no. Thaum cov kua nplaum tau qhuav lawm, thiab cov ceg tsis zoo tau khoov thiab xaum, nws yog lub sijhawm los txiav cov ceg zoo mus txog 5 hli, txiav ob txhais ceg ntawm txhua tus tiv thaiv kom txog tib qhov ntev.. Tom qab ntawd muab cov tshuaj tiv thaiv rau ntawm ob txhais ceg, kom nws zoo li daim duab thib ob, hauv qab no.. Kuv tau ua qhov no los ntawm rub lawv txhua tus ua ke thiab muab nws me ntsis ntswj. Tuav qhov kawg, tab sis tsis txhob txiav nws. Nws yog ib qho tseem ceeb tsis txhob cia cov ceg luv zoo khoov dhau kom txaus los kov cov choj tsis zoo. Yog tias qhov no tshwm sim, koj yuav tuaj yeem hais qhia vim tias LED uas nws txuas rau yuav tsis pom kev thaum lub sijhawm ntsuas tseem ceeb tag nrho. Ib daim kab xev insulating me me lossis ua tib zoo khoov yuav kho qhov no. Kev kawg, siv lub 8cm ntawm cov xaim hluav taws xob xaim mus rau qhov cim cim GND ntawm daim duab (lossis lwm yam ntsiab lus nkag siab uas tsis zoo ntawm ob txhais ceg txuas) Tam sim no yog lub sijhawm los ntsuas qhov ntsuas LED module! Muab peb lub tshiab D hlwb tso rau hauv rooj plaub roj teeb, thiab thawb lub ntsiab lus kawg ntawm pawg tiv thaiv mus rau qhov zoo. Tom qab ntawd, txiav qhov kawg ntawm cov xaim, siv nws rau cov hlau flange uas tawm los ntawm ntu hloov. Yog tias txhua yam zoo, nyem qhov hloov yuav tsum teeb lub LEDs … ua tiav! Yog tias tau kawg, qee qhov, feem ntau lossis tag nrho cov LEDs tsis pom kev, nws yog lub sijhawm ua qee qhov ua txhaum. Txheeb xyuas qhov luv ntawm cov xov zoo thiab cov choj tsis zoo uas tau ua yog tias ib lossis ob lub LEDs tsis pom kev. Tsis tas li, txheeb xyuas tias cov choj tsis zoo txuas mus rau lub qhov raug - txhua yam nws siv yog ib qho yuav tsum tau siv tsis raug thiab tag nrho ntu ntawm LEDs yuav tsis pom kev. Nws tsuas yog hluav taws xob hluav taws xob, txawm li cas los xij, yog li qhov laj thawj yuav tsum qhia tus neeg ua txhaum!
Kauj Ruam 3: Hloov Kho Lub Taub Hau
Qhov me me no txawv ntawm lub teeb rau lub teeb, thiab tau muab kev tu siab tshaj plaws rau kuv! Lub teeb uas pheej yig uas kuv tau yuav feem ntau yog tsim los ntawm cov roj hmab 'tsho loj' nrog (ua tau, ncaj me ntsis) yas ntxig rau cov qauv. txoj hauv kev yog kom muab lub teeb tso pov tseg, thiab siv cov hlau txuas kom yaj lub qhov hluav taws xob kom haum rau lub rooj tsav xwm hauv Circuit Court. Kuv kuj tau txiav plaub fab ntug tawm ntawm lub rooj tsavxwm nrog cov xaim txiav kom pab nws haum me ntsis zoo dua. Qhov zoo tshaj yuav yog rau cov qauv LED kom haum rau hauv lub teeb pom kev sib dhos kom lub teeb ntawm LEDs dag nrog lub hauv ntej ntawm lub tsom iav - qhov no yuav txhais tau tias nws tuaj yeem rov qab mus rau hauv lub lens sib dhos yam tsis muaj kev hloov pauv ntxiv. txawm li cas los xij, Kuv yuav tsum xaiv rau nyiag nkas ntawm lub tsom iav kom khaws cov xov rau hauv qab lub hau, thiab siv blu-tak los so tus qauv hauv nws. Kuv pom txoj hauv kev yooj yim tshaj plaws los 'txiav' lub teeb pom kev zoo rau qhov loj yog siv cov hlau kub kub yaj kom yaj nws, txiav tawm qhov tshaj nrog rab riam. Xyuas kom koj muaj qhov cua nkag tau zoo yog tias koj xaiv ua nws li no, vim nws tuaj yeem tso tawm qee cov pa phem. Yog hais tias lub rooj sib txoos tsom iav tseem zoo ib yam, qhov no yuav xav tau lwm lub qhov los ua hauv nws, txhawm rau tso cov kab tsis zoo mus txog lub phaj yam tsis mus ze qhov dav dav zoo. Tom ntej no txiav qhov 'zoo ceg' kom nws xis nyob ntawm lub caij nplooj ntoo hlav. kev sib cuag ntawm lub davhlau ya nyob twg zoo hauv lub hau ntswj. Txhawm rau pab txhawb qhov no, Kuv khoov lub davhlau ya nyob twg me ntsis kom nws tuaj yeem tau txais kev sib cuag hluav taws xob zoo li ua tau.
