Delete objects/variables

(I got a Python/Perl background, where nobody cares about memory management - except the developers of the languages.)

In the course of my sketch, I assign variables both primitive and complex (objects) values. The most common situation is as follows:

void loop()
{
  // ...
  SerialTuple request = SerialManager::receiveTuple();
  if(request.type == 1 and request.reference == 2)
    {
    int motorSpeed = request.getIntDataAtPos(0);
    // processing 'motorSpeed'
    };
  // both 'request' and 'motorSpeed' will not be needed further
  // ...
};

After some seconds, LEDs for RX, TX and on PIN 13 light up and the Arduino won't react anymore.

So how do I destruct, delete (or whatever one calls it) variables and free memory again?

Thanks

Because neither motorSpeed or request are pointers, the memory they are using will be freed when the variable goes out of scope. You don't have to do anything.
