Output from IC1 passes into the input of IC2 which is the popular Johnson Decade counter CD4017. It has 10 outputs. Of these 8 outputs are used. Output 9 ( pin9) is tied to the reset pin 15 to repeat the cycle. When the input pin 14 of IC2 gets low to high pluses, its output turns high one by one. Resistor R3 keeps the input of IC2 low in stand by state to avoid false indications.

Electronic Cricket Match Game
This electronic
cricket is a present for Kids. This simple battery powered circuit can be used
to play Cricket Match with your friends. Each LED in the circuit indicates
various status of the cricket match like Sixer, Run out, Catch etc. The Circuit
uses two ICs ,one in the Astable mode and the second in the display driver
mode. IC1 is wired as an Astable Multivibrator with the timing elements R1, R2
and C1. With the shown values of these components very fast output pulses are
generated from the Astable.

When the Push
Switch S1 is pressed momentarily, the Astable operates and all the LEDs run
very fast sequentially. When S1 is released, any one of the LED stands lit
which indicates the status of the match. For example, if LED D7 remains lit, it
indicates Sixer and if LED 8 remains lit, it indicates Catch out. Label each LED for its status as shown in the diagram. Pressing
of S1 simulates Bowling and Running LEDs indicates running of Batsman.
