Hi I am new to this site and new to electronics. But I would like to start building a scoreboard. The seven segment numbers would be about 12"x 9" in size and need to be in 3 blocks. 1 block would be 3 segments 0 to 999. next 1 segment of 2 blocks of 0 to 99 and a single 0 to 9. I have looked at the controllers and decided to use a 4510 bcd and a 4511. is this OK? All I what is to control the segment with a + button a - button and a reset. I need to know where the buttons are positioned on the PCB. Can any one post me a wiring diagram for this? As simple as possible.

Does block mean “groups of digits?”
Something like XXX----XX----XXX where each X is a digit?

Does a segment mean a digit? To display numbers (0 through 9)
each digit would require seven segments, much like a digital clock.

While its not ‘wrong’ you need to consider the
power (voltage and current) for each segment.
eddieg:
about 12"x 9"
That is huge, and will need many watts of power to
be daylight readable. Perhaps your size numbers
are wrong?
Remember, a sheet of paper (US letter size) is 8.5
x 11 inches. Lay some pages out on your kitchen
table to see if your project makes sense.

What PCB?
BTW, this isn’t really a PCB design question, perhaps you
can ask a mod to move your question to the projects forum?
This is somewhat ambitious for a newbee project.
I suggest you start simple and build scoreboard with a small 7 segment LED display. You will learn a lot and most of it will be directly applicable.
Once you gotten that working, you can replace the LED display with separate electronics that drives segments made up of incandescent (my guess) bulbs.
Or you could learn how to drive a 5x7 LED array for each digit - that’s more involved but will allow you to display letters AND numbers.
How ever you approach it, think modularly. have the score control separate from 7 segment (or array) control separate from display (LED or bulb) driving.
Also, if you are going to try and drive 120VAC lights, you need to take great care. One mistake can kill you.
