Abstract
Along with the technical and quick development in electronics, appear with the large-scale integrated circuit especially, give mankind the life brought the changes of the root. The coal gas reports to the police the system publishes, scribing the electronics measure the instrument walked into the arithmetic figure turns the ages its function is strong, the function is well-found, technique forerunner, will quickly technical development in science.
In the hardware aspect, except the monolithic outside the aircraft, uses ten seven section of led nixie tube s to carry on the demonstration, LED uses is the motionless scanning demonstration, uses the 74LS21 chip to carry on the actuation.
With the coal of compilation, we can get the functions of this design such as keeping scores, recording the time, and that we can alternate with the scores of both teams. It’s practical and simple to accomplish.
Key words: Single Chip Microcomputer ,led nixie tube ,keeping scores and the time
