Up down reset counter with 7 segment displays

[ARno]

Hello!

I'm one of those guys who immediately starts apoligizing for lacking knowlegde on electronic circuits.
Still I really want to start working on this, and I have a case for my table tennis club.
Paper score boards are like shit and some fabricators are earning a lot of money because they only last for one year.
I see a lot of threads on other websites, but none in the way I want to make my electronic scoreboard.
In order to (at least) have the right hardware, I really need your help. After I have the correct hardware, I can start programming.
If the circuit doesn't work, at least I know it is because of bad programming .

I hope the following functional diagram explains what I want. Can someone please give me a list on which hardware components i need?
Which controller gives me enough I/O and is the best solution?

Hey Arno,

First start with interface of segment with controller and multiplexing concept of interface seven segment.I suggest to you to link about segment interfacing:

Later you start to built your application.

If any queries,Let me know..

i m sorry

but i didnt get anything from the diagram that wht r u upto?

what u want to do exactly? how many displays u want to interface?

Allright, I think I'm wanting too much at the same time.

As said, I'm totally new on electronics and programming.
What I would like to build is a 'scoreboard' which has the following functions/indications:
Player 1:
1 x 2 digit 7 segment score (0-99) by up/down for points
1 x 1 digit 7 segment score (0-9) by up/down for sets
Player 2:
1 x 2 digit 7 segment score (0-99) by up/down for points
1 x 1 digit 7 segment score (0-9) by up/down for sets
What I would like to have is one reset switch which will result in resetting all above mentioned scores.

The above mentioned score is visible to the 'player-side', but off course the referee needs to be able to see and check the score also.
So the same amount of 7 segment displays need to be placed on the 'referee-side' of the scoreboard, and off course they should indicate the same scores as the player-side.

So off course I want to build the whole bunch in one time, but maybe it is better to start with only one up/down 2-digit 7segment counter and a reset function.
Does anyone have a instructable for a new-kid for something like this? I see a lot of them on the internet, but most of them are already too difficult for me.
I don't even know how to upload the code to the microcontroller, so I'm looking for a instructable on that low-educated level.

Please help me! I need to start somewhere

[Ashutosh Bhatt]

in that case there is not a single system

there is saparate up down counter with display for each player either 1-digit or 2-digit

u dont need common system like u have drawn in ur diagram

[ARno]

I see, so I four separate up/down counters with one overall reset switch.
As asked, does anyone have a low educated instruction / partlist for this?
 

[Ashutosh Bhatt]

search for simple 2-digit up/down counter on internet. u will get what u want

[ARno]

I did some research, but i'm missing some fundamental knowledge to choose a direction.

Am I correct if there are two ways to walk this path?
1) A programmable microcontroller like the PIC16F628
2) A non-programmable BCD like the 4510 together with a BCD to 7-segment decoder like the 4511

Is it correct to assum that option numer two doesn't need programming and only connecting the right pins?
I would prefer a non-programmable solution.

[Ashutosh Bhatt]

yes u r on right way

for simple counter u dont need programmable chip like micro controller

u can also use CD4033 or CD4026 chip which is better option

hi bro,

can u mail your details on my id [email protected] so i can help you out….
