Arduino开发环境中菜单栏下方的7个按钮依次是Verify(校验)、Stop(停止)、New(新建)、Open(打开)、Save(保存)、Upload(上传)、Serial Monitor(串口监视窗)。各按钮的具体功能如下: Verify(校验),用以完成程序的检查与编译。 Stop(停止),用以停止进行的编译操作。 New(新建),可新建一个程序文件。 Open(打开),打...
从Serial阅读数据并使用String（）函数将数据行转换为String后，可以使用sscanf()函数将值分配给所需的变...
Reads an analog input (potentiometer) on pin 0, prints the result to the serial monitor. OPEN THE SERIAL MONITOR TO VIEW THE OUTPUT FROM THE POTENTIOMETER >> Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground. ...
Reads an analog input pin, maps the result to a range from 0 to 255 and uses the result to set the pulsewidth modulation (PWM) of an output pin. Also prints the results to the serial monitor. The circuit: * potentiometer connected to analog pin 0. ...
打开Serial Monitor(串行监视器)。监视器应该不断显示消息,指示X、Y和Z轴的加速度。三个轴在加速度计上用小图表示。 图7 加速度计模块以及三个轴向 要测试加速度计,请在其中一个轴向上突然移动该模块。这时,该方向上的加速度分量会发生变化。 输出示例如下: ...

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。
演示如何使用模拟引脚读取来自某个传感器的输入：The following is a simple Arduino example. Demonstration of how to use analog pins to read the input from a sensor:```cpp// 定义一个变量来存储读取的值int sensorValue = 0;void setup() { // 初始化串口，设置波特率为9600 Serial.begin(9600);...
