Terminate a function and return a value from a function to the calling function, if desired.
return;
return value; // both forms are valid
value: any variable or constant type
A function to compare a sensor input to a threshold
int checkSensor(){ if (AnalogRead(0) > 400) {return 1;else{return 0;}}
The return keyword is handy to test a section of code without having to 'comment out' large sections of possibly buggy code.
void loop(){// brilliant code idea to test herereturn;// the rest of a dysfunctional sketch here// this code will never be executed}
