Los ntawm ElectropeakElectroPeak Lub Vev Xaib Ua Haujlwm Ntxiv Ntxiv los ntawm tus sau:

Txog: ElectroPeak yog koj qhov chaw ib-nres los kawm cov khoom siv hluav taws xob thiab coj koj lub tswv yim mus rau qhov tseeb. Peb muab cov lus qhia saum toj kawg nkaus los qhia koj li cas koj tuaj yeem ua koj cov phiaj xwm. Peb kuj tseem muab cov khoom lag luam zoo yog li koj muaj … Ntau Ntxiv Txog Electropeak »

Hauv kab lus no peb xav qhia koj yuav ua li cas txhawm rau txhim kho kev nyab xeeb ntawm koj cov ntaub ntawv digital khaws cia hauv lub hard drive los ntawm tus ntiv tes luam ntawv sensor thiab Arduino. Qhov kawg ntawm kab lus no koj:

Yuav kawm paub siv lub tshuab ntsuas ntiv tes li cas.

Yuav ua kom muaj kev nyab xeeb ntxiv rau koj lub hard drive.

Muaj peev xwm muab kev nkag tau rau cov neeg siv tshwj xeeb los siv koj li txhab nyiaj hauv txhab nyiaj.

Kauj Ruam 1: Txhim Kho Kev Ruaj Ntseg Ruaj Ntseg los ntawm Arduino & Fingerprint Sensor

Cov Ntaub Ntawv Ntug Dej Ruaj Ntseg

Lub hard disk drive (HDD), hard disk, hard drive, lossis disk ruaj khov, yog lub tshuab hluav taws xob cov ntaub ntawv khaws cia uas siv cov hlau nplaum khaws cia thiab khaws cov ntaub ntawv digital siv ib lossis ntau qhov nrawm nrawm rotating disks (platters) coated nrog cov khoom sib nqus. Cov platters tau ua khub nrog lub taub hau sib nqus, feem ntau tau teeb tsa ntawm lub caj npab txav, uas nyeem thiab sau cov ntaub ntawv mus rau qhov chaw platter. Cov ntaub ntawv tau nkag mus rau hauv kev nkag mus yam tsis tau nkag siab, txhais tau tias cov ntaub ntawv ntawm tus kheej tuaj yeem khaws lossis khaws cia hauv ib qho kev txiav txim thiab tsis tsuas yog ua ntu zus. HDDs yog ib hom uas tsis hloov pauv, khaws cov ntaub ntawv khaws tseg txawm tias thaum siv hluav taws xob. Flash nco yog lub tshuab hluav taws xob (khoom siv hauv lub xeev) uas tsis hloov pauv lub computer cia nruab nrab uas tuaj yeem tshem tawm hluav taws xob thiab rov ua dua tshiab. Toshiba tau tsim lub cim xeeb los ntawm EEPROM (hluav taws xob tshem tawm qhov programmable nyeem tau nkaus xwb) nyob rau xyoo 1980s thiab qhia nws mus rau tom khw hauv 1984. Ob hom tseem ceeb ntawm lub cim xeeb nyem yog lub npe tom qab NAND thiab NOR logic rooj vag. Cov tib neeg nco lub cim xeeb nthuav tawm cov yam ntxwv zoo ib yam li cov rooj vag sib xws. Thaum EPROMs yuav tsum tau muab tshem tawm ua ntej yuav rov sau dua, NAND-hom nyem lub cim xeeb tuaj yeem sau thiab nyeem hauv cov ntawv (lossis nplooj ntawv) uas feem ntau me dua li txhua lub cuab yeej. NOR-hom nyem tso rau ib lo lus tshuab (byte) sau-mus rau qhov chaw raug tshem tawm-lossis nyeem nws tus kheej. Yog tias koj siv hard drive lossis flash nco los khaws koj cov ntaub ntawv thiab lawv tsis muaj kev nyab xeeb ntawm lawv cov cuab yeej lossis software, txoj haujlwm no muaj txiaj ntsig zoo rau koj.

R301T Fingerprint Module

Cov ntiv tes hauv nws qhov kev nkag siab nqaim yog qhov ua rau pom los ntawm kev sib txhuam ntawm cov tib neeg cov ntiv tes. Kev rov qab los ntawm cov ntiv tes los ntawm qhov ua txhaum cai yog ib txoj hauv kev tseem ceeb ntawm kev tshawb fawb keeb kwm kev noj qab haus huv. Cov ntiv tes tau yooj yim tso rau ntawm qhov chaw uas tsim nyog (xws li iav lossis hlau lossis pob zeb ci) los ntawm lub ntuj tso tawm hws los ntawm cov qog eccrine uas muaj nyob hauv cov kab mob sab nrauv. Cov no qee zaum hu ua "Chanced Impressions". Hauv kev siv dav ntawm lub sijhawm, cov ntiv tes yog cov cim ntawm qhov kev xav los ntawm kev sib txhuam ntawm ib sab ntawm tib neeg lossis lwm tus npoj yaig tes. Ib qho luam tawm los ntawm ib txhais taw kuj tseem tuaj yeem ua rau muaj kev cuam tshuam ntawm kev sib txhuam. Hauv qhov haujlwm no Peb siv R301T sensor module uas ua kev sib txuas lus txuas nrog tus tswj xws li Arduino los pauv cov ntaub ntawv. Cia ua.

Kauj Ruam 2: Cov Ntaub Ntawv Xav Tau

Kauj ruam 3: Circuit Court

Kauj ruam 4: Code

Koj yuav tsum ntxiv cov ntiv tes ntsuas lub tsev qiv ntawv thiab tom qab ntawd tso cov cai. Yog tias nws yog thawj zaug uas koj siv Arduino board, tsis txhob txhawj xeeb. Tsuas yog ua raws cov theem no:

1. Mus rau www.arduino.cc/en/Main/Software thiab rub tawm Arduino software sib xws nrog koj li OS. Nruab IDE software raws li qhia.

2. Khiav Arduino IDE thiab tshem cov ntawv sau thiab luam cov cai hauv qab no hauv kab ntawv sau.

3. Xaiv lub rooj tsavxwm hauv cov cuab yeej thiab cov laug cam, xaiv koj li Arduino Board.

4. Txuas Arduino rau koj lub PC thiab teeb COM chaw nres nkoj hauv cov cuab yeej thiab chaw nres nkoj.

5. Nias lub pob Upload (Arrow sign).

6. Koj tau npaj txhij!

Cov ntaub ntawv tsim nyog thiab rub tawm:

Kauj ruam 5: Sib dhos

Ua ntej, Ua qhov txuas me me txuas los ntawm micro USB 3 lub qhov (socket). Txhawm rau nrhiav pom daim duab qhia chaw ntawm lub qhov (socket), siv pawg thawj coj saib xyuas ntawm Hard Drive.

Ua ib lub thawv nrog daim ntawv Acrylic (plexiglass) thiab muab lub vojvoog tso rau hauv. Saib cais tawm ntawm lub rooj tsavxwm thiab txuas nws mus rau Arduino ncaj qha.

Kauj Ruam 6: Dab Tsi Ntxiv?

Koj tuaj yeem txhim kho txoj haujlwm no raws li koj xav tau. Nov yog qee qhov lus qhia:

Sim khaws lub sijhawm sib txuas los ntawm txhua tus neeg siv hauv Arduino.

Sim los xam tus nqi ntawm cov ntaub ntawv xa los ntawm txhua tus neeg siv.
