int sensorValue = 0; // variable to store the value coming from the sensor
void setup() {
// declare the ledPin as an OUTPUT:
Serial.begin(9600);
}
void loop() {
// read the value from the sensor:
sensorValue = analogRead(sensorPin);
delay(1000);
Serial.print("sensor = " );
Serial.println(sensorValue);
}
result in different condition
