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.

int threshold = 40; for (int x = 0; x < 255; x++) { analogWrite(PWMpin, x); sens = analogRead(sensorPin); if (sens > threshold) { // bail out on sensor detect x = 0; break; } delay(50); }
