That’s fine!
In general, if the project concept is stable and it has a group of related questions, it is easier to keep adding follow-up questions to a big thread – that way people trying to help you can come up to speed in one place, and aren’t hunting around or re-asking similar questions in multiple threads. So “now that they stop, how do I make them bounce?” – same thread, because we need all the same info on what the class is. Completely disconnected part of the project – motion detection, vs random audio generation – different thread is fine.
