Circuit description
Power supply voltage: 4.5v-6v.
Function: 
when the power is turned on,7 leds will display a point at random. When the player presses the switch S1, all 7 leds will turn on. After a few seconds,7 leds will start flashing and finally show a stable point.The whole "roll of the dice" process is over.
The circuit is mainly composed of a pulse generator and a decimal counter circuit.The pulse generator is composed of NE555 and peripheral components to form a multivibrator. When pressing the button S1, Q1 is switched on. When the 3-pin output pulse of NE555 is pressed, the 5 output terminals of CD4017 take turns to output high level.Through different combinations of resistance and audion, 7 leds can be driven to emit light to indicate the number of 1-6.
