[@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); }
