Digital scoreboardcircuit functions to display values from 0 to 9 on the 7 segment display. 7 segments using a type of common anode. 7 segment driver IC using a 74LS47 or 74LS247. On thedigital scoreboardcircuitry uses a 555 timer ic, serves to produce a rate as to enter the 74LS192 counter IC.Digital scoreboardcircuits there are 3 switches, if the switch S1 is pressed then the 74LS192 will calculate forward. whereas if the switch S2 is pressed then the 74LS192 will count down. to switch S3 serves to return the counter value. Source voltage on the digital scoreboard is 9 volts. Here is a schematic drawing digital scoreboard:
