be free before the second thread. If now a third thread with a stack size of 64 bytes will be created it can not be placed before the second thread since only 63 bytes of memory are free. So it will be placed after the second thread and will cause 63 bytes of memory to be wasted...
Let me put it this way: if you have 25% left and 25% right it’s no different than having 0% left and 0% right because they get summed together before they’re sent to the PC. The PC won’t see any change so long as both axes are perfectly opposed. That has nothing to do ...

Whatever library the #include statement was calling for, you want to look through this big long list for a library with the exact same name. If you don’t see the file name there, this means the library isn’t installed. You’ll have to add that library before the sketch will compile...
