Nws yog qhov zoo uas tau pom koj dua ntawm no ntawm kuv lwm qhov kev qhia, ntawm no kuv yuav pab koj los tsim daim ntawv thov khoom lag luam yooj yim siv RFID RC-522 thiab Arduino nrog Ua kom tsim tau yooj yim GUI.

Nco tseg: tsis txhob khiav Arduino tus saib xyuas thaum khiav cov cai vim hais tias chaw nres nkoj tsis sib haum yuav tshwm sim vim ob leeg yuav tsum siv tib lub chaw nres nkoj

Koj Xav Tau:

1. Arduino Mega lossis Arduino Uno (Kuv siv Mega)
2. RFID-RC522
3. 7 txiv neej rau poj niam jumper xov hlau
4. Qee daim npav ID (xaiv tau)
5. RFID Lub Tsev Qiv Ntawv (Yuav tsum, Txuas Hauv Qab)
6. Wamp neeg rau zaub mov
7. Ua IDE 2.2.1 (tsis txhob siv ntau dua ntawd)
8. BezierSQLib-0.2.0 tsev qiv ntawv rau kev ua (Rub tawm txuas hauv qab no)

Tom qab ntawv Rub tawm Hauv qab no RFID lub tsev qiv ntawv thiab ntxiv nws rau koj Arduino IDE los ntawm txhaj Sketch-> Xws li Tsev Kawm Ntawv-> Ntxiv. Zip Library hauv cov ntawv qhia zaub mov

Kauj Ruam 1: Teeb Arduino thiab RFID RC-522 (Kev Sib Txuas Lub Cev)

yooj yim txuas cov arduino nrog RFID-RC522 raws li qhia hauv cov duab saum toj no. Warning: muab tsuas yog 3.3V txwv tsis pub module yuav hlawv tawm

Pin Out rau Uno/Nano thiab Mega

Kauj ruam 2: Arduino Code.,

Luam cov cai hauv qab no rub nws rau koj Arduino

Kauj Ruam 3: Teeb MySQL

1. Nruab Wamp server rau MySQL thiab teeb tsa nws kom khaws cov ntaub ntawv (
2. Khiav wamp serveropen MySQL console
3. xaiv database
4. Tom qab ntawd tsim lub rooj rau koj cov ntaub ntawv

tsim cov lus rfid (ID int (8), token int (1), Npe varchar (20), Tus nqi int (4));

Tam sim no saib qhov txuas no txhawm rau kawm paub yuav ua li cas kom tau txais koj li txiaj ntsig RFID lossis tom qab siv tus lej hauv qab no txhawm rau ntxig cov ntaub ntawv. Tsis txhob hnov qab hloov tus lej tus lej nrog koj tus lej cim npe RFID

ntxig rau hauv rfid qhov tseem ceeb (3756178, 1, 'Mem hluav', 20);

siv tus nqi token li 1 yog li ntawd tom qab nyeem tus lej cim thawj zaug nws yuav hloov pauv mus rau 2, tsis txhob siv 0 rau tus nqi token thaum nyeem daim npav uas tsis tau ntxig rau hauv DB nws yuav muab 0 tom qab ntawd tso nws ua Daim Ntawv Tsis Paub..

Kauj Ruam 4: Teeb Kev Ua Haujlwm IDE

1. Rub tawm thiab Txhim Kho Cov Txheej Txheem IDE 2.2.1
2. Tshem tawm cov ntawv ZIP saum toj no rau MyDocuments/Ua/Libraries
3. Tam sim no qhib kev ua IDE thiab tshawb xyuas lub tsev qiv ntawv tau teeb tsa raug lossis tsis zoo li hauv cov duab saum toj no
4. Tom qab ntawd Luam cov cai hauv qab no los ua thiab npe nws ntawm koj tus kheej
