Ob peb lub lis piam dhau los, Kuv xav tau ib qho chaw ntawm constant voltage 7v thiab tam sim no ntawm tam sim no hauv 5a. Nws nyob ntawm no tau mus tshawb rau qhov xav tau BP hauv kev taw qhia, tab sis qhov no tsis pom muaj nyob rau ntawd. Tom qab ob peb feeb, Kuv nco qab tias hauv qab ntawm txhais tes hauv thaub qab muaj lub computer muab khoom siv, thiab qhov no yog qhov kev xaiv zoo tshaj plaws! Muaj embarked rau lub hlwb sib sau ua ke hauv ib pawg ntawm cov tswv yim thiab tom qab 10 feeb tus txheej txheem pib.
Rau kev tsim cov chaw kuaj ntawm qhov ntsuas hluav taws xob tas li, nws yuav tsim nyog:
- Cov Khoom Siv Hluav Taws Xob Los Ntawm Computer
- Terminal Thaiv
- Lub teeb-emitting diode
- resistor ~ 150 ohms
- Tumbler
- Thaum Tshav Kub Kub Ntswg
- Khi.
Lub zog siv hluav taws xob yuav pom qhov chaw tsis xav tau. Nyob rau hauv cov ntaub ntawv ntawm kev nrhiav kev nrhiav tau - los ntawm $ 10. Pheej yig dua Kuv tsis tau pom. Cov khoom seem ntawm cov npe no yog kopeck thiab tsis yog tsis txaus.
Los ntawm cov cuab yeej koj yuav xav tau:
- nplaum phom A.K.a. Kub kua nplaum (rau LED Mounting)
- Soldering Hlau thiab Lwm Yam Khoom (Tin, Flux ...)
Txoj kev khi
- tho nrog txoj kab uas hla ntawm 5 hli
- Screwdrivers
- Sideboards (NIPPERS)
Tsim
Yog li, thawj qhov kuv tau raug tshuaj xyuas qhov kev ua tau zoo ntawm BP no. Lub cuab yeej tig mus ua tau zoo. Koj tuaj yeem txiav tawm cov ntsaws, tawm 10-15 cm ntawm lub plug sab, vim hais tias Nws tuaj yeem ua ke. Nws yog tsim nyog sau cia uas koj yuav tsum xam qhov ntev ntawm cov hlau hauv lub zog hluav taws xob kom nws txaus rau qhov chaw pub dawb hauv bp.
Tam sim no nws yog ib qho tsim nyog los faib txhua tus xaim. Rau lawv cov cim, koj tuaj yeem saib tus nqi, lossis cov chaw uas lawv mus. Cov chaw yuav tsum tau kos npe. Feem ntau, muaj feem ntau lees txais cov xim cim xim, tab sis cov chaw tsim khoom ntawm koj BP tej zaum yuav pleev xim xaim txwv tsis pub. Kom tsis txhob "kev tsis nkag siab" zoo dua xaiv cov xov hlau.
Ntawm no yog kuv "xaim gamma." Nws, yog tias kuv tsis yuam kev, thiab muaj ib tus qauv.
Nrog daj rau xiav, Kuv xav kom meej meej. Ob lub xim muaj txiaj ntsig li cas?
PG (Shod. Los ntawm "Hwj chim zoo") - cov xaim uas peb siv los txhim kho qhov ntsuas tau. Voltage - 5V.
Ntawm - xaim uas yuav tsum tau kaw nrog gnd kom tig rau lub zog hluav taws xob.

Nyob rau hauv lub hwj chim muab muaj xov hlau uas kuv tsis tau piav qhia ntawm no. Piv txwv li, violet + 5vsb. Peb yuav tsis siv cov hlau no, vim tias Tus ciam teb ntawm qhov tam sim no rau nws yog 1a.
Thaum cov xov hlau tsis cuam tshuam, koj yuav tsum tho ib lub qhov rau lub LED thiab ua ib daim ntawv nplaum nrog cov ntaub ntawv tsim nyog. Cov ntaub ntawv nws tus kheej tuaj yeem pom ntawm lub Hoobkas ntawv nplaum, uas nyob rau ib tog ntawm BP. Thaum drilling, koj yuav tsum tau saib xyuas tias cov hlau hlau tsis tau txais cov cuab yeej hauv lub cuab yeej, vim tias Qhov no tuaj yeem ua rau muaj kev cuam tshuam tsis zoo heev.
Kuv txiav txim siab los nruab ib lub davhlau ya nyob twg nyob rau pem hauv ntej vaj huam sib luag. Nyob rau hauv tsev muaj ib tug block ntawm 6 cov chaw, uas tau npaj rau kuv.
Kuv muaj hmoo, vim hais tias Lub slots nyob rau hauv bp thiab lub qhov rau mounting cov pads coincided, thiab lub taub mus ze. Txwv tsis pub, nws yog ib qho tsim nyog los tshawb cov kev txiav ntawm BP, lossis laum cov qhov tshiab hauv BP.
Cov ntaub qhwv tau ntsia tau, tam sim no koj tuaj yeem tshem tawm cov xov hlau, tshem kev sib cais, ntswj thiab xim av. Kuv tau kuaj 3-4 xaim ntawm txhua xim, tshwj tsis yog dawb (-5v) thiab xiav (-12v), vim tias Lawv nyob hauv BP ib los ntawm ib qho.
Thawj qhov yog lub teeb - coj cov hauv qab no.
Txhua cov xov hlau tau txais kev pab. Koj tuaj yeem clamp rau hauv lub davhlau ya nyob twg.
Nruab LED
Kuv tau coj cov lus qhia li ib txwm muaj. Ib qho kev qhia liab liab dog iab coj (nws muab tawm, me ntsis ci dua). Ntawm anode (ntev ceg, tsawg dua loj hauv lub taub hau ntawm LED) Peb ham), uas yog ua ntej cog nrog tshav kub ntsws. Ntawm cathode (luv ceg, ib feem ntau dua nyob rau hauv lub taub hau ntawm LED) Ua ntej tshaj plaws, thiab tawm ntawm cov hlau hlau (GND), uas Peb kuj tsis txhob hnov qab ua ntej tso lub tshav kub ntsws. Thaum txhua yam yog soldered, peb tig lub tshav kub ntsws ntawm cov lus xaus ntawm lub LED thiab ua kom sov.
Nws hloov tawm xws li ib yam. Muaj tseeb, Kuv muaj me ntsis overheated lub tshav kub ntsws, tab sis nws tsis txaus ntshai.

Tam sim no kuv txhim kho lub LED rau hauv lub qhov, uas kuv tho thaum pib.
Cov kua nplaum kub. Yog tias nws tsis yog, koj tuaj yeem hloov cov kua nplaum Super-nplaum.
Lub Tog Hluav Taws Xob Hloov
Qhov hloov mus Kuv txiav txim siab los nruab rau hauv qhov chaw uas lub zog hluav taws xob tau txuas ntxiv cov xov hluav taws sab nraud.
Ntsuas txoj kab uas hla ntawm lub qhov thiab khiav mus nrhiav rau toggle haum.
Kuv muaj ib qho kev ntaus me ntsis, thiab pom lub zoo meej hloov. Vim tias qhov sib txawv hauv 0.22mm, nws txig rau hauv qhov chaw. Tam sim no ntawm thiab gnd tseem nyob rau hauv chav pw, mam li nruab nws nyob rau hauv rooj plaub.
Cov haujlwm tseem ceeb tau ua. Nws tseem nyob nqa marafet.
Cov tw hlau tails uas tsis siv rau cais tawm. Kuv tau ua nws tshav kub ntsws. Cov xov hlau ib qho xim yog qhov zoo dua rau cais ua ke.
Txhua txoj hlua khau zoo nkauj nyob sab hauv.
Peb ntswj lub hau, tig mus rau, bingo!
Chav tsev no tuaj yeem tau txais ntau qhov kev ntxhov siab sib txawv uas siv cov peev xwm sib txawv. Nco ntsoov tias qhov kev txais tos no tsis yob rau qee cov khoom siv.
Ntawm no yog lub spectrum ntawm kev nyuaj siab uas tuaj yeem tau txais.
Hauv kev nkhaus, thawj yog zoo, qhov thib ob yog qhov tsis zoo.

- Siv cov ntaub qhwv nws tus kheej, raws li siv cov kev piav qhia ntawm no nrog cov menyuam yaj uas ua kom txaus, kom tsis txhob txaus rau hauv tes ntawm kev thuam ib zaug ntxiv.
