[导读]射频通信是物联网应用中最常用的通信技术之一，我们之前在两台Arduino之间的通信中使用了433 MHz的射频模块。在本教程中，我们将使用NRF24L01收发模块在Arduino板和NodeMCU之间进行无线通信。在这里，我们将使用NodeMCU ESP8266从互联网服务器获取实时时间戳 ...

[导读]有各种无线通信技术用于构建物联网应用，RF(射频)是其中之一。nRF24L01是一款工作在2.4 - 2.5 GHz (ISM频段)的单片无线电收发模块。该收发模块由一个完全集成的频率合成器、一个功率放大器、一个晶体振荡器、一个解调器、一个调制器和增强的ShockBurs协议 ...

刚开始学ARDUINO的时候做的，现在分享出来。 接收机这一块没有单独做，直接使用ARDUINO UNO，接上NRF24L01无线射频模块，烧录好程序就可以作为接收机来使用，（PS:接收程序根据需要自己改）。 CC0805KRX7R9BB104贴片电容精度：±10% 容值：100nF 额定电压：50V 温漂系数 ...
