+ | ====== 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 ==== | ||
+ | <code arduino> | ||
+ | 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); | ||
