1.RFID简介2.RFID-RC522模块介绍二、如何使用1.硬件部分2.软件部分2.1三、如何使用总结前言很久以前就想做一个使用NFC卡来开关门锁的小玩意,找了很多案例都没有找到合适的,网上教的人也比较少于是只能慢慢摸索,学习速度很慢,在这里我将用一个小案例来说一说Arduino的RFID模块的使用.一、RFID是什么?1.RFID简介...
Prices vary from USD 7 for clones, to USD 75 for "starter kits" (which might be a good choice if this is your first exposure to Arduino; check if such kit already includes the Arduino, Reader, and some Tags). Proximity Coupling Device (PCD): The PCD is the actual RFID Reader based...
It is a modern identification device used in various places such as offices and universities. It comprises a RFID (MF-RC522) reader and a tag, if a valid tag is put in front of the reader the access is allowed otherwise the access is denied. This setup is consisting of Arduino-Nano, ...
