Serial Monitor (Arduino)

SERIAL MONITOR

Upload the following sketch to your Arduino. Later on, we will see exactly how it works. _____________________________________________________________
  

/*

 AnalogReadSerial

  Reads an analog input on pin 0, prints the result to the serial monitor.
  Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.

// the setup routine runs once when you press reset:  

 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:
  int sensorValue = analogRead(A0);

 
  // print out the value you read:

  Serial.print("Sensor Value=");
  Serial.println(sensorValue);

 
  delay(1000);        // Interval between readings = 1 second }

After you have uploaded this sketch onto your Arduino, click on the right-most button on the toolbar in the Arduino IDE. The button is circled below.

The following window will open. You can see a steady stream of numbers ranging from 0-1023, correlating to the position of the potentiometer. As you turn your potentiometer, these numbers will respond almost instantly.

This window is called the Serial Monitor and it is part of the Arduino IDE software. Its job is to allow you to both send messages from your computer to an Arduino board (over USB) and also to receive messages from the Arduino. It is a separate pop-up window that acts as a separate terminal that communicates by receiving and sending Serial Data.
