turning on and off a light emitting diode(LED) connected to digital pin 13. The amount of time the LED will be on and off depends on the value obtained by analogRead(). The circuit: * Potentiometer attached to analog input 0 * center pin of the potentiometer to the analog pin * one ...
Arduino板上有多个模拟引脚（通常标记为A0-A5），可以用来读取模拟信号。In Arduino, analog input usually refers to the voltage value from the sensor, buttons, or other analog device through the analog pins of Arduino. There are multiple simulation pins on the Arduino board (usually marked as A0-A5...
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》
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. ...

1数字输入/输出端口：Arduino板上有14个数字输入/输出端口（Digital I/O），标记为0~13。其中0和1号端口分别用于串行通信，可以与计算机进行通信；2~13号端口可以用作数字输入或数字输出，具体用途取决于编程代码的实现。2模拟输入端口：Arduino板上有6个模拟输入端口（Analog Input），标记为A0~A5。
这时，我们可以在Arduino IDE里编入以下代码：void setup() { // initialize serial communication at 9600 bits per second:Serial.begin(9600);} // the loop routine runs over and over again forever:void loop() { // read the input on analog pin 0:float sensorValue = analogRead(A0);// convert...
