analogRead Serial Monitor with Potentiometer


Reads an analog input on pin A0, prints the result to the serial monitor.

Connections:
Attach the center pin of a potentiometer to A0, and the outside pins to +5V and ground


Code :


//Analog Read with Serial Monitor

void setup() {
  //the setup routine runs once when you press reset

  Serial.begin(9600); //initialize serial communication at 9600 bits per second
}

void loop() {
  //the loop routine runs over and over again forever

  int sensorValue = analogRead(A0); //read the input on analog pin 0

  Serial.println(sensorValue); //print out the value you read

  delay(10); //delay in between reads for stability
}
