no vote
The whole program is controlled by en switch. When en is 0, the student number will be displayed. When en is 1, the program will start to run. When en is 1, the program starts to run, four lights start to light up randomly, and start the 30 second countdown. The nixie tube displays the remaining time, score and current difficulty. Press one of the buttons. If the hamster matches the button, it will be regarded as hitting the hamster. The score will be increased by one and the indicator light will be on. Otherwise, the indicator light will be on for a long time. When the countdown is over, the game is over, and the score is no longer counted, and the nixie tube displays the result. Open sw17 to view the top three historical results. Turn on switch SW2 to reset, turn off to restart the game. Sw16 can be turned on or off to select the difficulty level. &The whole program consists of eight main modules: frequency division module, random number generation module, comparison module, nixie tube display module, scoring module, history record module and countdown module.
