.. _arduino-return:
return
======
Terminate a function and return a value from a function to the
calling function, if desired.
Syntax:
-------
return;
return value; // both forms are valid
Parameters
----------
value: any variable or constant type
Examples:
---------
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 here
return;
// the rest of a dysfunctional sketch here
// this code will never be executed
}
