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


for (x = 0; x < 255; x ++)
    digitalWrite(PWMpin, x);
    sens = analogRead(sensorPin);
    if (sens > threshold){      // bail out on sensor detect
       x = 0;
       // this line of code means that we'll immediately exit
       // from the "for" loop:
