I've tried everything but I don't understand at all how to apply threads. Please, someone kind could give me an indication of how to do it right? I have tried several examples and the result is always the same. The "stop" button does not stop until the "ping" loop has finished. Please, I'm a newbie, give me a simple explanation of how to apply the thread
