1. 添加第二个电磁锁,以保证两侧锁门。 2. 在门上添加一个霍尔效应(磁传感器)传感器和一块磁铁,以便让Raspberry Pi在锁门之前知道门已返回到关闭位置。 3. 如果你真的很有想法,那么可以围绕门设计较大的环形天线,代替在门上安装小型读卡器。你需要电磁线,而且需要将其焊接到读取模块上。这需要资深技巧,有关环形...
连接到Pi的示意图和布局 对于真正整洁的工作,请将读取器安装在木制或塑料盒中,最好使用尼龙螺钉,因为紧密的金属会减小读取范围。 将阅读器连接到Pi后,就该获取需要阅读的软件了。 首先,您必须在连接到Internet的Raspberry Pi的终端窗口中键入sudoapt-getinstall python-dev来安装python-dev系统。 git clonehttps://g...
您需要更改一些默认配置才能将其连接到 Raspberry Pi,默认情况下,Raspberry Pi 禁用了 SPI(串行外设接口),这有点问题,因为我们的 RFID 读取器电路就是这样运行的。所以你必须改变这个。 . l. 让我们去你的 Raspberry Pi 终端并编写 sudo raspi-config sudo raspi-config 流此以更改您的设置 一些默认设置更改 ...
wiringPi库为我们提供了用软件多线程实现的PWM输出,我们能够利用这个库提供的函数非常方便的将随意GPIO配置为PWM输出。在本例中。我将GPIO0,GPIO1。GPIO2配置成了soft PWM输出。树莓派的引脚分配表例如以下图所看到的: 我用的RGB LED是共阴极的,与树莓派的连接方式例如以下: Raspberry Pi RGB LED module GPIO0-...
