 Another challenge was to not halt the main loop when we want to say something.
-For example if we want to
+For example if we want to say the ``twenty five'' we would love to simply call the functions as \\
+play(twenty); play(five); \\
+But unfortunately the mp3 module we used does not have a queue functionality so what would actually happen is that the first few milliseconds of the ``twenty'' are getting played, but then it gets stopped and instead ``five'' is being played.
+For this reason we needed to implement our own queue.
+We simply have a global list of integers (by default all of them are zero), a global variable that saves the current playing index, and a global variable that saves the current end index of the queue.
+We then one function that gets called on every loop.
+It checks whether the mp3 module is still busy.
+If it is not any more, it looks if there is a file to play at the current playing index.
+If there is (indicated by a non-zero entry), then we start playing that file, and increment
+the current playing index.
+We have another function for adding files to the queue.
+It simply puts the number of the file to play at the current end index of the queue,
+and increments the queue.
+Both index variables get set back to zero in case they reach the the end of the queue.
