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',
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...
/*Analog input, analog output, serial outputReads an analog input pin, maps the result to a range from 0 to 255 and usesthe result to set the pulse width modulation (PWM) of an output pin.Also prints the results to the Serial Monitor.The circuit:- potentiometer connected to analog pin ...
