## break

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

#### Example

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