The 13th simulation problem of the single chip microcomputer provincial competition of the Blue Bridge Cup
2022-07-01 18:26:00 【Miseñor】
This time, it's still iic The channels of the photosensitive and potentiometer are interchanged , I don't know why , I also encountered such a situation when I was doing the national games last time （ See other articles on my blog ）, Now I don't know why , I hope some big guys can answer questions and dispel doubts .（ All functions have been realized ）
