2. What are the difficulties and challenges you might have?

I think that it would be a bit difficult to actually set a specific time to set the schedule for the user’s dog(s) because I have a feeling that my partner and I can only program one schedule for the user’s dog(s)on a microbit. I also think it might be challenging to change the schedule because I don’t think microbit allows you to program a microbit to change something without using the microbit website.
