Predict the output of the following code if the object is moving towards the sensor.
int op = 6;
int isBarrier = HIGH;
void setup() {
pinMode(op, INPUT);
Serial.begin(9600);
}
void loop() {
isBarrier = digitalRead(op);
if (isBarrier == LOW) {
Serial.println("1+");
}
else {
Serial.print("clear+");
}
delay(100);
}
A)
B)
C)
D)
Explanation:
As the object moves towards the sensor, it will block it, causing the sensor to read LOW, which prints 1+. If the object moves away, it will read HIGH, printing clear+.
Output: (A) clear+clear+1+1.
