Siv tus nas kho qhov muag kom pom duab qis. Daim duab no yog tus "e" hauv qab nas.

Kauj Ruam 1: Kev tshoov siab rau Txoj Haujlwm

Kuv tau saib ntawm nplooj ntawv no: kho qhov muag nas cam thiab cov lus ntawm cov neeg uas xav ua nws tab sis tsis paub yuav ua li cas ntxiv. Thaum kuv tau txais txiaj ntsig qhov ua tsis tau zoo nas nas kuv qhib nws thiab pom tias nws muaj tib lub sensor zoo li hauv nplooj ntawv web saum toj no. Yog li kuv tuaj yeem rov ua nws txoj haujlwm, thiab siv software uas nws tau tsim los. Qhov duab qhia pom lub rooj tsavxwm sab hauv nas yam tsis hloov kho.

Kauj Ruam 2: Tshem Tus Tswj Xyuas Chip

Thaum koj tau txais koj tus nas, qhib nws. Qhov kho qhov muag pom tau tuaj yeem ua qhov txawv los ntawm qhov nws nyob saum lub lens. Nws yuav tsum muaj yim tus pin, thiab muaj cov cim ntawm lub hnub ntawm nws, thiab tseem muaj cov ntawv sau "A2610". Hauv qhov xwm txheej ntawd, nws yog Agilent ADNS2610 kho qhov muag nas sensor, zoo ib yam li siv los ntawm spritemods, thiab (tom qab) los ntawm kuv. Yog tias nws muaj ntau dua yim ceg, lossis tus lej sib txawv, cov lus qhia no yuav tsis ua haujlwm.

Ntawm no, Kuv tau tshem tus tswj lub nti thiab txuas ob qhov txuas kom cov cim qhia los ntawm lub ntsuas hluav taws xob hla ncaj. Peb lub khawm khawm tau raug tshem tawm los siv hauv qee qhov haujlwm. Aluminium electrolytic capacitors tau hloov pauv nrog tantalum capacitors ntawm qhov qub, tab sis me dua.

Kauj ruam 3: Lub Sensor

Daim duab qhia pom ze ntawm lub nti sensor thiab kuv tau sau cov pins raws li daim ntawv teev npe.

Kev sau ntawv ntawm kuv tus nas sensor hais tias "A2610 C0517C" thawj qhov yog tus lej, thiab qhov thib ob tej zaum yog hnub tim thiab mfg code. Peb yuav tsum txuas mus rau Vdd, Gnd, sck thiab sdio pins (nyem rau ntawm daim duab kom pom nws puv loj).

Kauj Ruam 4: Hauv Qab ntawm Pawg Thawj Coj

Daim duab qhia pom hauv qab ntawm pawg thawj coj saib. Lub ntsuas qhov muag tau tiv thaiv nrog kab xev me ntsis.

Kuv tau sau daim ntawv thib ob kab lus. Thaj chaw gnd yog thaj tsam tooj liab loj tshaj plaws ntawm lub rooj tsavxwm. Vdd tuaj yeem lees paub los ntawm qhov muaj lub tshuab hluav taws xob hluav taws xob ncaj qha hla nws thiab gnd.

Kauj Ruam 5: Lub Tshuab Luam Ntawv Txuas

Hla mus rau lwm sab, koj xav tau qhov chaw nres nkoj (centronics), uas feem ntau hu ua chaw nres nkoj tshuab luam ntawv, hauv koj lub computer. Ntawd yog 25 tus pin D txuas, ntawm plaub kab siv.

Ntawm daim duab, Kuv tau cim plaub kab uas tau siv. Yog tias koj saib ze, koj yuav pom tias cov pins tau sau nrog cov lej.

Kauj Ruam 6: Kev Tsim Kho - Haum rau Diode

Koj xav tau lub diode, piv txwv li 1N4148. Muab nws tso nrog qhov kawg nrog cov qhab rau tus pin 5 ntawm tus txuas. Ntawd yog, cathode ntawm diode mus rau tus pin 5.

Kauj Ruam 7: Lwm Qhov kawg ntawm Diode

Tam sim no siv cov xaim hlau (lossis siv cov hlau lead ntawm diode nws tus kheej) thiab txuas rau lwm qhov kawg ntawm diode rau tus pin 12. Ntawd yog, qhov anode ntawm diode txuas rau tus pin 12.

Tam sim no kos nws. Tus Pin 12 yog qhov kawg tab sis ib qho, thiab muaj rau tus lej pub dawb ntawm nws thiab tus pin 5, qhov twg lwm qhov kawg ntawm lub diode tau tsau.

Kauj Ruam 8: Txuas Cable

Kuv siv ib daim flatcable los ntawm cov kab tsav nyuaj los txuas cov laug cam rau lub tshuab luam ntawv txuas. Cov lej hauv daim duab hauv qab no hais txog tus lej tus lej ntawm lub kho qhov muag sensor nti.

Nws yog qhov zoo tshaj los txheeb xyuas cov xov hlau uas siv lub multimeter, lossis qee yam kev ntsuas txuas mus ntxiv uas yuav tsis ua rau lub nti nti puas. Tus pin 3 ntawm lub sensor yog cov ntaub ntawv hauv/tawm tus pin. Nws mus rau tus pin txuas 12 ncaj qha, thiab rau tus pin 5 ntawm lub diode. Pin 4 ntawm lub ntsuas cua yog lub moos nkag. Nws mus ncaj qha rau tus pin 9 ntawm tus txuas. Pin 6 ntawm lub sensor yog hauv av. Nws txuas rau thaj tsam loj ntawm tooj liab ntawm lub rooj tsavxwm, thiab tus pin 25 ntawm tus txuas. Tus pin 7 ntawm lub sensor yog tus pin muab. Nws yuav tsum tau muab nrog +5 volts rau lub sensor ua haujlwm. Hauv daim duab, qhov no yog xaim daj, khiav rov qab mus rau lub hard drive txuas. Yog tias koj muaj thawj kab ntawm nas, txawm hais tias USB lossis PS/2, tsib kab hluav taws xob yuav nyob ntawm qhov kawg. Tsuas yog txheeb xyuas qhov ntawd thiab txuas rau nws.

Kauj Ruam 9: Ua Kom Nws Ua Haujlwm

Thaum nws txuas nrog mus rau qhov chaw nres nkoj sib luag, lub software yuav tsum rub tawm thiab khiav kom pom qhov tso tawm ntawm lub computer screen. Txoj haujlwm hu ua "Readmouse" thiab muaj nyob ntawm no. Nws yog zip archive uas yuav tsum tau rub tawm, unzipped, thiab tom qab ntawd ua raws cov lus qhia hauv cov ntaub ntawv readme. Cov ntaub ntawv ntawm lub sensor muaj nyob ntawm no yog tias koj tau txais lub sensor sib txawv thiab xav hloov kho qhov program los ua haujlwm nrog qhov ntawd. Daim duab qhia pom qhov tso tawm ntawm kuv lub koob yees duab nas thaum siv ua lub tshuab luam ntawv ntawm nplooj ntawv uas muaj qee qhov luam tawm. Kuv xav tias Kuv yuav txuas ntxiv siv kuv lub tshuab luam ntawv ib txwm, tom qab tag nrho.
