Hauv qhov haujlwm no kuv yuav qhia koj yuav ua li cas kom tau txais cov ntaub ntawv los ntawm RFID (Xov Tooj Cua Zauv Cim) module rau lub xov tooj Android, koj tuaj yeem siv nws los saib sab hauv cov txheej txheem ntawm kev txheeb xyuas daim npav RFID, vim nws tuaj yeem ua rau khaus kom paub yog tias daim npav tab tom nyeem kom raug lossis tsis yog tias tsis muaj cov khoom tso tawm kom pom cov ntsiab lus.
Cia Pib Pib!
Kauj Ruam 1: Yam Yuav Tsum Tau
Nov yog yam koj xav tau thiab txuas rau cov khoom lag luam -
1.) Nyeem Ntawv RFID
2.) RFID Cim npe
3.) Arduino
4.) Tus Xov Tooj Android
5.) Jumper Hlau
6.) HC-06 Bluetooth Module
Kauj ruam 2: Tsim
RFID tus qauv yuav tsum txuas nrog Arduino hauv txoj hauv kev kom pab tau SPI kev sib txuas ntawm ob qhov no, cov xov hlau nyuaj dua li qhov peb ib txwm ua hauv kev cuam tshuam xws li I2C tab sis, peb ua qhov kev sib pauv no vim xav tau kev sib txuas lus ceev ntawm microcontroller piv txwv li Arduino thiab RFID module.
Nov yog cov hauv qab no koj txuas cov qauv rau Arduino -
SDA ------------------------ Digital 10SCK ----------------------- -Digital 13
MOSI ---------------------- Digital 11
MISO ---------------------- Digital 12
IRQ ------------------------ tsis txuas nrog
GND ----------------------- NCO
RST ------------------------ Digital 9
3.3V ------------------------ 3.3V (Tsis txhob txuas rau 5V)
Tam sim no, koj yuav tsum rub tawm thiab teeb tsa lub tsev qiv ntawv MFRC522 hauv Arduino IDE thiab xa cov piv txwv "AccessConrol" mus rau Arduino. Ib zaug rub tawm qhib lub vijtsam txuas mus kuaj thiab luam theej duab.
Yog tias txhua yam mus raws li tau hais, koj zoo rau txuas Bluetooth Module HC-06 mus rau Arduino raws li teeb tsa hauv qab no.
TX - Rx
Rx - Txi
Tswv yim - 5V
Gnd - Yog
Kauj Ruam 3: Xeem
Tam sim no koj tsuas yog yuav tsum teeb tsa daim ntawv thov saib xyuas ntawm koj lub xov tooj Android thiab txuas nws mus rau HC-06 module, thaum koj tau ua tiav, koj yuav pom cov zis los ntawm RFID module thaum koj luam theej duab RFID cim npe.
Yog tias koj xav pom yuav ua li cas txoj haujlwm ua haujlwm tiag tiag Kuv xav kom koj saib cov vis dis aus qhia rau qhov haujlwm no txuas nrog hauv intro.
Ua tsaug rau koj nyeem qhov no deb !!

Tsim kom muaj Wearable Motion Tracker (BLE Los Ntawm Arduino mus rau Custom Android Studio App): 4 Cov Kauj Ruam
Tsim kom muaj Lub Teeb Meem Tracker (BLE Los Ntawm Arduino mus rau Custom Android Studio App): Bluetooth Tsawg Zog (BLE) yog ib daim ntawv ntawm kev sib txuas lus tsis muaj zog Bluetooth. Cov cuab yeej siv tau, zoo li cov tsoos tsho ntse kuv pab tsim ntawm Predictive Wear, yuav tsum txwv kev siv hluav taws xob txhua qhov chaw tuaj yeem ua kom ntev lub roj teeb, thiab nquag siv BLE
Plotting Real-time Graph ntawm Android Los Ntawm Arduino Los Ntawm HC-05: 3 Cov Kauj Ruam
Plotting Real-time Graph ntawm Android Los ntawm Arduino Los ntawm HC-05: Hav nyob ntawm no, ntawm no yog kev qhia qhia yuav ua li cas npaj cov phiaj xwm ntawm lub sijhawm tiag tiag ntawm qhov tseem ceeb los ntawm tus tswj hwm micro xws li Arduino rau lub app. Nws siv Bluetooth qauv xws li HC-05 los ua lub cuab yeej xa xov mus rau kis thiab tau txais cov ntaub ntawv ntawm Ar

Arduino Programming Via Mobile -- Arduinodroid -- Cov Arduino Lub Tswv Yim rau Android -- Blink: 4 Cov kauj ruam
Arduino Programming Via Txawb || Arduinodroid || Cov Arduino Lub Tswv Yim rau Android || Blink: Thov sau npe yuav ua kuv li youtube channel rau ntau cov yeeb yaj kiab …… Arduino yog pawg thawj coj, uas tuaj yeem ua haujlwm ncaj qha rau ntawm USB. Nws yog qhov yooj yim heev thiab pheej yig rau kev ua haujlwm hauv tsev kawm qib siab lossis tsev kawm ntawv lossis txawm tias yog cov qauv khoom lag luam. Ntau yam ntawm cov khoom ua ntej tsim rau nws rau kuv
