Is it profitable and especially possible to create a somewhat intelligent cat food dispenser?
@Camila_99$$ Each project makes sense. If you want to make some profit from manufacturing it in the future, I would start with some research on alibaba.com, 1688.com, taobao.com or similar servers. They probably sell much better devices that you can even design.

Hello. In my opinion, you need all 6 inputs. You could go with 5, when connecting both EN inputs. You need the fast motor stop option. This means that both C and D cannot be controlled only inversely, but you need the possibility to drive them at the same logical level.
