Reading valus: High and Low? ?

Dear Becky, thanks for great introduction course for MCUs.

My question is why Arduino can only read values High and Low`?, why not medium or something in the middle?`how actually reading values works?

It so simple Arduino can read any value it depends on which you are using for reading value if you using "digitalwrite" it take only high or low because digital mean only high or low.

In "analogwrite" function It can take any value i think may be from -255 to 255
