说明：  开机通电时，7只LED会随机显示一个点数，玩家按一下开关S1,7只LED会全部变亮，大约几秒后,7只LED灯开始闪烁，直到最后显示出稳定的点数。整个一次“掷骰子”的过程结束。 电路主要由脉冲产生器和一个十进制计数器电路组成。脉冲产生器由NE555及外围元件构成多谐振荡器，当按下按键S1时Q1导通，NE555的3脚输出脉冲，则CD4017的5个输出端轮流输出高电平，通过电阻和三极管的不同组合，可驱动7只LED发光，以指示1-6的点数。 这是一个纯硬件电路，包含原理图PCB图，适合初学数字电路的新人，增加趣味性。
(When the machine is turned on, 7 LED will randomly display a point, and the player presses the switch S1,7 only LED will be all brightened, and about a few seconds later, the 7 LED lights start to flicker until the final number of stable points is displayed. The whole process of "throwing the dice" ended. The circuit is composed of a pulse generator and a decimal counter circuit. The pulse generator consists of a multi harmonic oscillator with NE555 and peripheral components. When the Q1 is switched on when the button is pressed S1, the 3 foot of the NE555 output pulse, then the 5 output ends of the CD4017 output high level. Through the different combinations of the resistance and the triode, the 7 LED luminescence can be driven to indicate the number of 1-6 points. This is a pure hardware circuit, including schematic PCB diagram, which is suitable for beginners who are beginners in digital circuits.)
