在万能板上制作了基于单片机的LCD1602显示的秒表控制系统样机，使用

A prototype of the stopwatch control system displayed on the LCD1602 based on the single-chip microcomputer was made on the universal board, and the system simulation was completed using protus. The hardware and software were debugged separately, and the software and hardware were jointly debugged. Finally, the prototype was successfully debugged and the graduation was completed. The requirements of the design task book.
