SCM relatively smaller, and very light, development of more simple, cheap, environmentally basically no excessive requirements, and more importantly, it has good flexibility and stability, the ability of anti-jamming special strong. Because bination of the above soa bit microcontroller, so the current domestic purposes, SCM has been widely used by businesses, which are more prominent in mechatronics equipment, industrial automation and control, smart instrumentation, power electronics, automatic detection , household appliances and soon. SCM has many series, and 51 single-chip microcontroller is therefore the most representative one. In this graduation project will be through prehensive understanding to STC89C51 chip-based, coupled with the associated circuit implementation, the simple design ofa digital electronic clock, which is powered DC power supply, through the digital the accurate time display, through the relevant key on the time to adjust time.
