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.

Circuit Building Steps:
Mount two different ICs :
555 of 8 pin and CD 4017 of 16 pins on Bread Board.
Connect pin 1 of IC 555 to Ground and pin 4 of IC 555 to VCC. Pin 8,11,13 of CD 4017 to Ground.
Connect pin 8 of IC 555 and pin 16 of CD4017 to VCC. To operate IC555 in astable mode short pin 2 and 6 of IC by using common wire as shown in figure. In case CD4017 short pin 9 an 15 to make IC as decade Counter IC.
Mount Electrolyte Capacitor C1 on Bread Board. Connect its negative terminal of C1 to Ground.
Connect Positive terminal of C1 to pin 2 of IC 555.
Mount Resistor R1 and R2 of value 12K ohm on Bread Board. To obtain resistance of 12k mount resistors of value 10K and 2.2 K Ohm in Series as shown in diagram.
Connect one terminal of R1 and R2 resistor to pin 6 and 7 of IC 555.
Mount Switch Sw1 on Bread Board.
Connect one terminal of SW1 to VCC and another to R1.
Connect pin 3 of 555 to pin 14 of CD 4017 through wire as shown in diagram.
Mount eight different color LEDs on bread Board Connect cathode terminal of each LED into horizontal slots shown in diagram.
Mount Resistor R4 of 100 ohm on Bread Board. Connect its one terminal to cathode of all eight LEDs.
Connect second terminal of R4 to Ground.
Connect pin 3 of CD 4017 to anode of LED1 through blue wire.
Connect pin 2 of CD 4017 to anode of LED2.
Connect Anode of LED3 to pin 4 of CD 4017.
Connect pin 7 of CD 4017 to anode of LED4.
Connect pin 10 of CD 4017 to anode of LED5.
Connect pin 1o CD 4017 to anode of LED6.
Connect pin 5 of CD 4017 to anode of LED7.
Connect pin 6 of CD 4017 to anode of LED 8.
Connect Battery to the circuit as shown in diagram.
Press switch Sw1 once and see which leds glows. Like Cricket each LED gives us different information indication. Such as:
- LED1 is ON – This informs us that single run is taken.
- LED2 is ON – This informs us that two runs are taken.
- LED3 is ON – This informs us that three runs are taken.
- LED4 is ON – This informs us that Boundry is scored.
- LED5 is ON – This indicates six.
- LED6 is ON – This indicates wide ball.
- LED7 is ON – This indicates NO ball.
- LED8 is ON – This indicates fall of wicket.
