ADC - ARM using LM35

/*

This Arm board contains 12 ADC channels.Here output of temperature sensor is connected PE0 pin(A3) and ADC resolution 805 uV (12 BIT ADC) .Here i have set Maximum reference voltage of 3.3V .Since it is 12 bit we get 4096 Quantization levels and the data readed from temperature is sent to pc using uart protocol

*/

void setup() 

{

  Serial.begin(9600); // Sets the baud rate at 9600

}

void loop()

{

  int temperature = analogRead(A3)/13;  //reads the temperature

  Serial.print(temperature);

  Serial.write(0xd);

  delay(1000); //READS DATA IN EVERY ONE SECOND
