Arduino Water Sensor Set Up and Programming

SOURCE CODE:

const int waterSens = A0; //define water sensor const int led = 9;//define led to pin 9 int waterVal; //define the water sensor value

void setup() { pinMode(led, OUTPUT); //set led as an output pinMode(waterSens, INPUT);//set water sensor as an input Serial.begin(9600); //start the serial port at 9600 bauds

}

void loop() { waterVal = analogRead(waterSens); //read the water sensor Serial.println(waterVal); //print the value of the water sensor to the serial monitor if (waterVal <= 0){ digitalWrite(led, HIGH);//if the water sensor senses water turn the led on } else{ digitalWrite(led, LOW);//if it doesn't sense anything turn the led off } }
