When the machine is powered on, the seven LEDs will display a random number of points. The player presses the switch S1, and the seven LEDs will all light up. After a few seconds, the seven LEDs will start to flash until the stable number of points is displayed. The whole process of "rolling dice" is over.
The circuit is mainly composed of a pulse generator and a decimal counter circuit. The pulse generator consists of the NE555 and peripheral components to form a multivibrator. When the key S1 is pressed, Q1 is on, and the three pins of the NE555 output pulses, then the five output terminals of the CD4017 output high levels in turn. Through different combinations of resistors and triodes, seven LEDs can be driven to emit light to indicate the number of points from 1 to 6.
