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...
int sensorValue = analogRead(A0); // print out the value you read: Serial.println(sensorValue); delay(1); // delay in between reads for stability } 这段代码是Arduino编程语言编写的,用于读取模拟输入引脚A0上的值,并通过串行监视器(Serial Monitor)打印出来。 代码功能 读取模拟输入:代码通过连接到...

The serial monitor will only show once you print some output from your program. To change this behavior,see below. The Arduino Mega has multiple hardware Serial ports. You can connect the Serial monitor to a different serial port by configuring the pins in diagram.json. For instance, to conn...
Arduino开发环境下的串口监视器原来监控串口的通讯状况。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。

Serial.println() 是 Arduino 中的一个函数,它可以用来向串行窗口(Serial Monitor)打印信息。这个函数可以在Arduino的Loop()函数中调用以将信息发送到窗口中。它的语法是: 其中data 可以是任何欲打印的东西,包括字符串、整数和浮点数等。 Serial.println() 主要用于调试和测试,通过打印状态,速度和其他变量来了解程序...
