AnalogRead()

int analogRead (uint8_t pin)  	

Read the analog pin

Read the analog pin, and return the value in [0-1023]. Each reading will takes 1ms.

• Parameter:

pin Number of the pin

• Return:

Value during 0 to 1023.

• Example:

int analogPin = 3;     // potentiometer wiper (middle terminal) connected to analog pin 3
                       // outside leads to ground and +5V
int val = 0;           // variable to store the value read

void setup()
{
  Serial.begin(9600);          //  setup serial
}

void loop()
{
  val = analogRead(analogPin);    // read the input pin
  Serial.println(val);             // debug value
}
