Qhov kev qhia no yog thawj zaug tshaj tawm ntawm High Voltages.
Kauj Ruam 1: Vim Li Cas Peb Thiaj Li Yuav Tsum Tshawb Pom Qhov Muaj lossis Tshem Tawm Ntawm Daim Npav RFID?
Feem ntau ntawm kev qhia RFID hauv is taws nem yuav qhia koj li cas nyeem daim npav RFID. Tab sis qhov ntawd yuav tsis qhia koj thaum lub cim npe tsis nyob. Piv txwv li, hauv RFID raws li kev tuaj koom, peb tsis tas yuav paub ntev npaum li cas daim npav nyob ntawd. Tseem, rau qee kis, peb yuav tsum paub tias daim npav nyob lossis tshem tawm. Piv txwv li, hauv 6 lub tswm ciab ua si, nws yog qhov tsim nyog yuav tsum tso tag nrho cov tswm ciab ntawm qhov chaw tshwj xeeb rau qhov ua rau muaj txiaj ntsig. Rau daim npav ntawd hauv qab tswm ciab yuav tsum nyob ntawm txoj haujlwm ntawd. Txwv tsis pub, nws yuav cuam tshuam qhov ua ntu zus. Peb yuav siv Arduino thiab mfrc522 los kawm lub tswv yim no.
Kauj Ruam 2: Tshawb Nrhiav Tshem Tawm Cov Ntawv Cim RFID
Hauv qhov kev qhia no, peb tab tom yuav sau tus lej uas ntawm kev txheeb xyuas daim npav yuav qhib rau Ntsuab LED. Thiab thaum peb tshem daim ntawv, nws yuav tua Green LED. Tsis tas li, cov txiaj ntsig yuav tshwm ntawm tus saib xyuas. Koj tuaj yeem hloov kho txoj cai thiab siv nws rau ntau lub hom phiaj. Suab zoo? Cia peb pib.
Kauj Ruam 3: Peb Yuav Xav Li Cas?
Peb yuav tsis xav tau cov npe khoom rau qhov kev qhia no. Yog tias koj ua raws kuv cov vis dis aus thiab sim kuv cov kev qhia, koj yuav twb muaj Arduino Uno, MFRC522 RFID nyeem ntawv, Jumper xov hlau, Tsis siv neeg Breadboard, thiab LEDs. Koj tsis ua raws kuv cov lus? Tsis txhob txhawj; Kuv muaj daim duab rau koj.
Kauj Ruam 4: Arduino MFRC522 cuam tshuam
Tom qab txuas MFRC522, txuas LED rau tus pin D7 thiab GND.
Kauj Ruam 5: Kev piav qhia Code thiab Video Qhia
nrhiav code ntawm High Voltages
Kauj Ruam 6: Xaus
Los ntawm ua raws cov lus qhia no, koj yuav tuaj yeem paub tias RFID ua haujlwm li cas, yuav ua li cas cuam tshuam nrog RFID module nrog Arduino, thiab yuav ua li cas txhawm rau txheeb xyuas qhov tshem tawm ntawm RFID cim npe.

Qhov Sib Txawv Ntawm (Lwm Yam Tam Sim No & Tam Sim No Tam Sim No): Txhua tus paub tias hluav taws xob feem ntau yog Dc, tab sis li cas txog lwm hom hluav taws xob? Koj puas paub Ac? AC sawv rau dab tsi? Puas yog nws siv tau DC? Hauv txoj kev tshawb no peb yuav paub qhov sib txawv ntawm hom hluav taws xob, qhov chaw, daim ntawv thov
