Analog input, analog output, serial output 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 pi...
可以在代码最后使用 Serial.println() 命令: Serial.println(sensorValue); Now, when you open your Serial Monitor in the Arduino Software (IDE) (by clicking the icon that looks like a lens, on the right, in the green top bar or using the keyboard shortcut Ctrl+Shift+M), you should see ...
Also prints the results to the Serial Monitor. 读取模拟输入针,将结果映射到 0 至 255 并使用上面的结果来设置脉宽调制到输出针。 同时将结果也打印到串口监视器。 The circuit: 电路连接: - potentiometer connected to analog pin 0. Center pin of the potentiometer goes to the analog pin. ...

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。
