hi, im an engineering student and also new to MATLAB. Actually im having problem to plot the data from arduino in real time. For testing purpose im using arduino AnalogSerialInOut coding.
/* 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 pin 0. Center pin of the potentiometer goes to the analog pin. side pins of the potentiometer go to +5V and ground * LED connected from digital pin 9 to ground created 29 Dec. 2008 Modified 4 Sep 2010 by Tom Igoe This example code is in the public domain. */// These constants won't change. They're used to give names// to the pins used:const int analogInPin = A0; // Analog input pin that the potentiometer is attached toconst int analogOutPin = 9; // Analog output pin that the LED is attached toint sensorValue = 0; // value read from the potint outputValue = 0; // value output to the PWM (analog out)void setup() { // initialize serial communications at 9600 bps: Serial.begin(9600); }void loop() {// read the analog in value:sensorValue = analogRead(analogInPin); // map it to the range of the analog out:outputValue = map(sensorValue, 0, 1023, 0, 255); // change the analog out value:analogWrite(analogOutPin, outputValue); // print the results to the serial monitor:Serial.print("sensor = " ); Serial.print(sensorValue); Serial.print("\t output = "); Serial.println(outputValue); // wait 10 milliseconds before the next loop// for the analog-to-digital converter to settle// after the last reading:delay(10); }
Anyone please can help me?
