我们以前使用nRF24L01与Arduino来构建一个手势控制的机器人,在这里我们将简单地将nRF24L01与Arduino Uno连接,以无线方式从DHT11传感器发送和接收温度和湿度数据。 Arduino Uno没有任何内置的无线通信支持,如蓝牙或Wi-Fi,但它可以很容易地与其他Wi-Fi或无线模块接口,如LoRa, nRF,蓝牙,可用于构建基于物联网的应用程序。...
当按下开关时,Arduino板在其引脚D3上收到一个Arduino中断。在程序中,我们将声明Arduino的数字引脚3不断检查其输入电压。如果输入电压低,则将对讲机保持在接收模式;如果数字引脚号3高,则将对讲机切换到发送模式,以通过微控制器发送麦克风过程拾取的语音信号,然后通过NRF24L01 + PA + LNA带有外部天线发送。 第6步:电...
If you look at the specs of the ATMega328, which is the heart of the Arduino Uno, you’ll understand why I used A0. It turns out the the “analog” pins on an Arduino can also function quite well as digital I/O pins. I needed an extra pin for my L298N motor controller and I...
Here’s how it works: [fridaay] holds a transmit circuit that consists of an Arduino UNO, an accelerometer module, and an nRF24L01 transceiver, all running on a 9 V battery. Whenever [fridaay] jumps, the accelerometer reads the change in Z and sends it to the receiving circuit, which ...
