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);
    }
