2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:31

Yog tias koj lub khoos phis tawj lub khoos phis tawj lub suab txuas tau txuas nrog lub tshuab hluav taws xob sab nraud, thiab koj nkees nkees un/ntsaws nws thiab hloov nws rau/tawm, koj yuav nyiam cov lus qhia no.

Kauj Ruam 1: Txhim Kho Koj Lub Amplifier thiab Lub Suab nrov nrov

Kuv muaj lub Desktop PC uas kuv tau khaws los ntawm cov khoom pov tseg thiab uas kuv tau hloov lub niam ntawv nrog ib qho uas kuv tau txais los ntawm kuv tus nus.

Nws yog AMD 1.2 GHz processor nrog 256 MB thiab 8 GB HD. Lub txee yog qub Compaq Prolinea 4/25s uas muaj 486SX ntawm nws. Nws tau siv qee lub zog los hloov kho lub motherboard tshiab, tab sis tam sim no nws ua haujlwm. Kuv nyuam qhuav yuav lub suab nrov nrov ntawm lub khw muag khoom rau 1 US $. Kuv tsis nyiam qhov tseeb tias kuv yuav tsum ntsaws/ ntsaws tig rau/ Tawm qhov txhua txhua lub sijhawm kuv xav saib DVD lossis yeeb yaj kiab kuv dowloaded los ntawm Youtube Yog li kuv xav txog kev teeb tsa lub rooj sib hais lub suab nrov thiab hais lus hauv lub txee, tab sis tom qab ntawd kuv yuav tsum tau laum ntau qhov rau On/Off hloov. Yog li vim li cas thiaj tsis muaj kev tswj hwm virtual hauv XP los qhib/Tawm lub amp, yog li kuv tuaj yeem siv kuv lub mloog pob ntseg thaum hmo ntuj lossis kuv tus neeg hais lus nruab hnub? Ntawm feem ntau cov niam ntawv uas muaj daim npav suab hauv lawv, muaj qee qhov chaw uas cov pab pawg ntawm cov pins lossis cov chaw nyob uas lub suab IN/OUT tuaj yeem tau txais. Kuv nyuam qhuav ua qee lub suab paj nruag thiab siv lub tswv yim ntawm lub suab nrov kom pom cov pins uas muaj lub suab tso rau. Koj kuj tseem tuaj yeem google lub vev xaib rau koj tus kheej tsim thiab ua qauv thiab rub tawm cov qauv los txuas koj lub suab nkag mus rau sab xis. Yog li tshem cov ntawv luam tawm Circuit board thiab tus hais lus los ntawm koj lub tshuab raj thiab mountem hauv koj lub pc lub txee. Xyuas kom lub rooj tsavxwm tsis txhob kov cov hlau ntawm nws (siv cov khoom sib xws, zoo li cov yas yas) thiab ntsia nws. Tom qab ntawd koj yuav xav tau qhov no: -A 12 VDC (coil) relay -A low power NPN transistor (like 2N2222 or BC548) -A low power diode (Like 1N4148 or 1N4001) -A 1kOmh -4.7kOhm low power resitor. -Some xov hlau -Solder -Paste -Soldering hlau

Kauj ruam 2: Txuas txhua yam

Ua ntej kuv tau teeb tsa kuv tus neeg hais lus thiab lub rooj sib hais lub zog sab hauv, siv 12 VDC txuas mus hloov 110 VAC muab rau nws.

Tom ntej no kuv siv lub zog qis NPN transistor (zoo li BC584), lub zog qis diode txhawm rau txhawm rau rov qab emf los ntawm kev xa tawm, thiab 1kOhm resistor rau kev tsis ncaj ncees tsav lub transitor lub hauv paus Kuv siv 12 VDC muab los ntawm cov khoom seem harddisk/floppy txuas.

Kauj Ruam 3: Xaiv Tus Pin Los Ntawm Koj Qhov Chaw Nkag Nkag

Kuv siv 12 VDC cov khoom siv los ntawm cov khoom siv khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khawm thiab siv tus pin 9 los ntawm qhov chaw nres nkoj sib luag (me ntsis 7) los tsav lub transisor.

Koj muaj 8 tus pin los siv (2-9) sib xws rau 8 khoom ntawm chaw nres nkoj LPT1. Koj tuaj yeem siv ib qho ntawm cov no. Koj tuaj yeem siv tus so co tswj cov khoom sab nraud yav tom ntej. Nrhiav txoj hauv kev los yog ncoo qhov twg tus pin koj xaiv tau mus rau thiab muab tshuaj txhuam koj cov resistor nyob ntawd (yog li yog tias koj luv kab, tsis muaj dab tsi puas tsuaj). Tom qab ntawd muab nws tso rau ntawm lub hauv paus transistor. Zoo li hauv

Kauj Ruam 4: Ua Koj Txoj Haujlwm

Tam sim no koj xav tswj kev xa tawm los ntawm Windows. Yog li koj xav tau Visual Basic lossis lwm yam software programming zoo li C lossis Delphi.

Kuv nyiam Visual Basic, Yog li kuv tsuas yog rub tawm dawb los ntawm Lub Vev xaib cov ntaub ntawv Inpout32.dll uas kuv xav tau los cuam tshuam qhov chaw nres nkoj sib luag. Nws yuav tsum tau theej rau koj Windows/System32 phau ntawv teev npe thiab tom qab ntawd koj tsuas yog ua tus qauv hauv koj qhov VB txoj haujlwm rau kev tshaj tawm ntawm ob txoj haujlwm IN/OUT. Kuv qhov program tsuas muaj ib lub pob uas koj toggle thiab nws teeb tsa me ntsis 7 (tus pin 9) On/Off yog li hloov qhov txuas. Yog tias koj muaj kev paub dhau los hauv VB, koj tuaj yeem nyiam nws lossis tsuas yog luam kuv cov npe, kuv yog qhov yooj yim heev vim nws tsuas muaj ib lub pob toggle On/Off tus pin. Tom qab ntawd koj tsuas yog tsim cov ntawv.exe. Raws li tau qhia hauv lub rooj sab laj, kuv tau ntxiv.zip cov ntaub ntawv nrog VB txoj haujlwm, lub tsev qiv ntawv, thiab suav sau. Exe cov ntaub ntawv npaj los ua haujlwm.

Kauj Ruam 5: Xeem Nws

Thaum koj tau sim nws, koj tuaj yeem tsim koj cov ntawv ua tiav. Koj kuj tseem yuav xav tso qhov luv ntawm koj li Startup directory, yog li nws tau thauj khoom thaum pib. Nov yog qhov kuv saib:
