这段代码用于读取连接在数字引脚2上的按钮(pushbutton)的状态,并将结果通过串行监视器(Serial Monitor)打印出来。 /* DigitalReadSerial Reads a digital input on pin 2, prints the result to the serial monitor This example code is in the public domain. */ // digital pin 2 has a pushbutton attached...

使用前需要先进行设定，设定的方法如下： 1.在Tool==>Serial Port里面选择Arduino的串口编号 2.在Tool==>Serial Monitor里面打开串口监视器 3.工具你程序的设定，在右下角的速度选择框里。

进入“Tools”->“Serial Monitor”,将baud rate设置为“115200”,然后按RST按钮检查串口连接。 步骤四、 清除 flash 根据生产批次的不同,部分开发板可能内置了预设的B&T固件,固件信息如下图所示: 固件位于 OTA 部分。所有新编译的固件将被 OTA 固件自动替换。因此,需要先清除 OTA 固件才能使用已编译的固件。 方...
Serial.println(sensorValue); 现在,当你打开Arduino IDE的串口监视器,你会看见“0”的数据流(如果开关打开)或者“1”的数据流(如果开关闭合) /* DigitalReadSerial Reads a digital input on pin 2, prints the result to the serial monitor This example code is in the public domain. ...
现在可以在 Serial Monitor 或 Arduino IDE 上监控结果,如下所示: 通过使用 ESP32 的双核同时运行多个任务,可以构建像实时系统这样的复杂应用。 #include "DHT.h" #define DHTPIN 13 #define DHTTYPE DHT11 const int led = 2; DHT dht(DHTPIN, DHTTYPE); ...
