digital scoreboard circuit


Posted on Feb 5, 2014

Digital scoreboard circuit 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 the digital scoreboard circuitry uses a 555 timer ic, serves to produce a rate as to enter the 74LS192 counter IC. Digital scoreboard circuits there are 3 switches,
