Here are the 4 elementary tasks

Basic Tasks of a Microcontroller

  1. Takes command (+, _, *, and /) from the user via keyboard/switch (input device);
  2. Takes data from the user via keyboard (input device);
  3. Modifies data in a way the user wants (say, adding two numbers); and,
  4. Delivers the result to the user via 7-segment/LCD display device (output device).

I think the word “basic” is surprising.

Those are not low level instructions, they are already in the real user world (I assume this might apply to your specific kit where you have a keypad and a 7segment?) but if you go there you could give other more general examples as Microcontrolers are way more capable than this (you listed before scale or taxi meter which is the use of sensor to make reading from the real world for example but can also fly drones etc).
