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.
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 Circuit Diagram
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.
