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:
break;
}
delay(50);
}
