Code?

[@erickgoldberg8153]

int LED = 13;
int MQ2pin = A0;
void setup()
{
Serial.begin(9600);
}
void loop()
{
float sensorValue;
sensorValue = analogRead(MQ2pin);

if(sensorValue >= 250)
{
digitalWrite(LED, HIGH);
Serial.print(sensorValue);
Serial.print(" ");
}
else
{
digitalWrite(LED, LOW);
Serial.print(" ");
Serial.print(sensorValue);
}

delay(1000);
}
