Kev cuam tshuam ntawm RFID-RC522 Nrog Arduino MEGA Cov Duab yooj yim: 4 Cov Kauj Ruam

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29

Hai nyob hauv qhov kev qhia no kuv yuav pab koj nrog cuam tshuam nrog RFID-RC522 nrog Arduino Mega 2560 los nyeem RFID thiab Zaub Cov Ntaub Ntawv ntawm Tus Saib Xyuas. yog li koj tuaj yeem nthuav nws ntawm koj tus kheej

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)

Tom qab ntawv Rub lub Tsev qiv ntawv hauv qab no 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: Kev Sib Txuas Lub Cev

yooj yim txuas cov arduino nrog RFID-RC522 raws li qhia hauv daim duab saum toj no.

Ceeb toom: muab tsuas yog 3.3V txwv tsis pub lub module yuav hlawv tawm

Pin Out rau Uno/Nano thiab Mega

Kauj Ruam 2: Txoj Cai Yooj Yim Nyeem thiab Sau Cov Ntawv Cim RFID

Luam cov cai hauv qab no rub nws rau koj Arduino

Luam cov cai hauv qab no rub nws rau koj Arduino. hauv qab no tag nrho tus nqi yuav khoom yuav nce ntxiv thaum nyeem daim npav thawj zaug thiab txo qis thaum nyeem tib yam rau zaum ob …
