Control questions
(CSDN electric competition, Blue Bridge Cup competition questions
For engineering design questions, refer to the previous electronic games and learn the knowledge of microcontroller control )...
The third round of interviews is an engineering question interview. You will be given a question, a draft paper, and let you design at the door for 10 minutes, and then go in and tell the teacher, try to introduce as detailed as possible, the content is substantial, the function is complete, and remain humble, not humble or overbearing.
