This is simple scoring game circuit and is useful like dice.

It uses IC555 timer, IC 74LS192 counter, IC 74LS247 decoder and 7-segment display.

IC 555 makes clock pulses and its speed is set by R1 and C2.

When we press S2 the counter goes up.

When we press S3 the counter goes down.

IC3 decoder shows number on display.

How to play:

Switch ON power and press S1 to reset.

Press S2 or S3 and release and the counter will stop at a number.

Press S4 the number will shows on display and that will be our score.

Next player will also repeat the same.

Always press S1 before new person tries and then press S2 or S3, then press S4 to see score.

Circuit works with 9V battery or DC supply.

It is simple counter circuit which is good for beginners and is easy to make.
