Arduino - Return - Weblessons

return

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}
