Kev tsim kev tshoov siab ntawm lub tswm ciab Circuit Court no yog los ntawm peb lub neej. Hauv peb lub hnub yug, peb yuav tsum teeb lub tswm ciab nrog lub teeb thiab tom qab ua qhov kev cia siab peb tshuab cov tswm ciab tawm. Qhov DIY Circuit no ua haujlwm zoo ib yam. Raws li peb tuaj yeem pom los ntawm cov phiaj xwm hluav taws xob, tag nrho cov Circuit Court yog tsim los ntawm ob txoj kab hluav taws xob sib txuas, ib qho yog lub tshuab hluav taws xob txuas hluav taws xob uas tau tsim los ntawm 9013 NPN transistor thiab 9012 PNP transistor thaum lwm qhov yog qhov hloov hluav taws xob uas tau tsim los ntawm photodiode thiab 9012 PNP transistor.

Cov txheej txheem ua haujlwm ntawm Circuit no yog raws li hauv qab no:

Nyob rau hmo ntuj, siv 4.5V txog 5V DC lub zog rau hauv Circuit Court, tsis muaj ib yam yuav tshwm sim kom txog thaum lub teeb cig luam yeeb tau los ze rau lub photodiode, cov xim LED uas muaj xim zoo nkauj yuav pib ntsais muag. Thaum koj tshuab mus rau lub mini microphone, LED yuav raug tua.

Kauj Ruam 1: Solder cov Resistors rau PCB

Ntxig cov resistors rau hauv lawv txoj haujlwm sib xws ntawm PCB. Txhua txoj haujlwm nws muaj nws tus nqi tiv thaiv tsis pub luam tawm hauv cov duab plaub dawb. Yuav ua li cas kom tau tus nqi tsis kam ntawm cov resistors? Muaj ob txoj hauv kev yooj yim rau lub hom phiaj no. Ib tus tau nyeem los ntawm cov xim xim luam tawm ntawm lawv lub cev, xav paub ntau ntxiv thov xa mus rau blog no. Lwm qhov yog qhov ncaj heev uas yog ntsuas nws tawm los ntawm multimeter. Tsuas yog yuav tsum ua raws daim duab 1 txog duab 4 kom ua tiav cov theem no. Koj yuav tsum tau ceev faj ntawm qhov me me spikes tsim los ntawm kev txiav tawm cov ceg ntau dhau ntawm cov tiv thaiv raws li qhia hauv duab 3 thiab duab 4.

Kauj Ruam 2: Solder Cov Khoom Siv Hluav Taws Xob rau PCB

Ntxig rau 102 thiab 103 thiab 104 cov khoom siv hluav taws xob rau hauv PCB thiab tom qab ntawd muab tshuaj txhuam. Txhua txoj haujlwm sib xws ntawm cov khoom siv hluav taws xob muaj nws cov khoom muaj nuj nqis luam tawm hauv lub duab plaub dawb. Thov xyuas kom tsis txhob tau txais cov khoom siv hluav taws xob tso rau hauv qhov chaw tsis raug.

Kauj Ruam 3: Siv lub NPN thiab PNP Transistors rau PCB

Ib yam li tau qhia hauv daim duab 7, txhua lub transistor muaj nws tus lej qauv luam tawm ntawm lub tiaj tiaj. S9012 yog PNP transistor thaum S9013 yog NPN transistor. Thov muab lawv tso rau hauv ib nrab voj voog dawb ntawm PCB. Cov transistors yuav tsum tau muab tso rau hauv ib nrab ib ncig nrog tib tus lej tus lej luam tawm ntawm PCB raws li cov transistors lawv tus kheej.

Kauj Ruam 4: Muab lub Photodiode tso rau thiab cov yeeb yuj LED rau PCB

Photodiode yog dab tsi? Lub photodiode yog cov cuab yeej siv hluav taws xob uas hloov lub teeb mus rau tam sim no. Qhov tam sim no tau tsim tawm thaum cov photons tau nqus hauv photodiode. Ib qho me me ntawm qhov tam sim no tseem tsim tawm thaum tsis muaj lub teeb pom kev. Photodiodes yuav muaj cov ntxaij lim dej kho qhov muag, tsom iav qhov muag, thiab tej zaum yuav muaj thaj tsam loj lossis me. Photodiodes feem ntau muaj lub sijhawm teb qeeb dua vim tias lawv thaj chaw nce ntxiv.

Lub photodiode yuav tsum tau muab tso rau hauv D2 thaum lub teeb pom kev zoo LED yuav tsum tau muab tso rau hauv D1. Cov ceg ntev ntawm ob qho ntawm cov photodiode thiab cov xim LED yuav tsum tau muab tso rau hauv lub qhov ze ntawm '+' cim.

Kauj Ruam 5: Muab lub Potentiometer thiab Mini Microphone rau PCB

Ua raws daim duab 12 thiab daim duab 13 txhawm rau ntxig lub hwj chim thiab lub microphone me me rau hauv PCB. Thov nco ntsoov tias sab saum toj saib ntawm lub microphone me me yuav tsum sib phim rau lub voj voog dawb luam tawm ntawm PCB.

Kauj Ruam 6: Muab CD4013 Flip-Flop IC rau PCB

Ib yam li zoo li cim hauv daim duab 14, lub voj voos hollowed ntawm lub ntsej muag ntawm CD4013 yuav tsum tau muab tso rau hauv tib qho kev qhia ntawm ib nrab ib nrab me me hauv qhov dav ntawm cov duab plaub dawb. Thaum koj thawj zaug tau txais tsuas yog hais txog ib qho DIP IC, ob txhais ceg yuav tsis zoo ib yam rau lub cev nti loj. Ob txhais ceg yuav khoov me ntsis. Hauv kuv qhov kev paub, nws yog qhov zoo tshaj los kho lawv ua ntej sim nkag mus rau hauv IC qhov (socket). Nws yog ib qho tseem ceeb heev uas cov kauj ruam no ua tiav nrog kev saib xyuas, kom tsis txhob ua puas rau cov chips. Mus qeeb, siv lub teeb nrawm, thiab siv koj lub sijhawm. Nkag mus rau IC nrog 2 txhais tes thiab ua kom cov pins ua raws li lub desktop. Koj xav khoov tus pin tib lub sijhawm kom lawv khoov txoj cai qhov pins hloov los ntawm dav mus rau nyias, siv qeeb, khov kho, thiab txawm tias siab kom khoov lawv tag nrho ib zaug kom txog thaum lawv mus ncaj ntawm lub nti.

Kauj Ruam 7: Xeem

Thov los ntawm 4.5V DC rau 5.0V DC mus rau lub hwj chim chaw nres nkoj, J1. Ignite lub teeb nyob ze ntawm photodiode, koj yuav pom cov yeeb yuj LED pib ua haujlwm. Yog tias koj xav kom lub LED raug tua, tsuas yog xav tau tshuab rau ntawm lub micro microphone. Nov yog lub voj voos los sim ua cov txheej txheem ntawm taws tswm ciab thiab tshuab tswm ciab tawm, nws tuaj yeem siv los ua ib qho kev qhia ua ntu zus los nthuav mus rau ntau lub teeb LED hauv koj qhov tshwj xeeb kev kho kom zoo nkauj.
