Arduino 英文教学04《Analog Inputs》 是在优酷播出的教育高清视频,于2012-05-18 08:24:39上线。视频内容简介:Arduino 英文教学04《Analog Inputs》
int analogPin = 5;int val = 0;void setup(){Serial.begin(9600);}void loop(){val = analogRead(analogPin);Serial.println(val);}这里还是要实现Matlab的即时读取和画图。Matlab代码如下:s = serial('COM3'); %定义串口对象set(s,'BaudRate',9600); %设置波特率sfopen(s); %打开串口对象sinterval...
X = readSensors(); //给X赋值 }while(X <100); //当x小于100时,继续运行,当x不小于100的时候就不运行了 2.7 break break用于退出do,for,while循环,能绕过一般的判断条件。它也能够用于退出switch语句。 例子 for (x = 0; x < 255; x ++) ...

We then got a mile-high overview of two of the core concepts of electricity: Ohm's law and circuits. We kept it simple and hopefully didn't lose anyone along the way. In this chapter, we will learn a bit more about analog input using a device that lets us set a dial angle ...

2、模拟输入 - Analog Input In this example we use a variableresistor(a potentiometer or a photoresistor), we read its value using one analog input of an Arduino board and we change the blink rate of the built-in LED accordingly. The resistor's analog value is read as a voltage because ...
