int mq3_analogPin = A0; // connected to the output pin of MQ3

void setup()
{
	Serial.begin(9600); // open serial at 9600 bps
}
void loop()
{
	//give ample warmup time for readings to stabilize
	int mq3_value = analogRead(mq3_analogPin);
	Serial.println(mq3_value);
	delay(100); //Just here to slow down the output.
}
