break

[Control Structure]

Description

break is used to exit from a for, while or do…​while loop, bypassing the normal loop condition. It is also used to exit from a switch case statement.

Example Code

In the following code, the control exits the for loop when the sensor value exceeds the threshold.

for (x = 0; x < 255; x ++)
{
    analogWrite(PWMpin, x);
    sens = analogRead(sensorPin);
    if (sens > threshold){      // bail out on sensor detect
       x = 0;
       break;
    }
    delay(50);
}
