Hey everyone.
*into*
I have experimented with a lot of electronics and other projects over the years. I have played with Arduino when it first came out, but got sidetracked with life.
All of sudden I got an arduino board on my hands and now Round 2 starting.
*end-into*

Project I am looking to start with.
A 2X 3or4 digit scoreboard with a button control (+/- points). (3or4 digit per "side").
Currently Have only arduino Uno but from my looking around I might need a bigger goat.
I am hoping to make/assembly majority/all components mainly for sake of making things.

I have this 2 paintings that I don't really like, was going to use them. Put LED's behind the paintings, eventually change the painting so that the LEDs go thru. I can hide the wiring as needed,
for the 2 controllers position is flexible.

I am sure I am missing a lot on the concept of the project, hope some one can point in the right direction.
Any and ALL suggestions are appreciated.

  • Which Arduino board do you have?
  • What kind of displays are you contemplating for the digits?  LED or LCD?  Matrix or 7 segment?
  • What will cause the scores to increment?  Can they decrement?
  • How will you reset?


If you multiplex the digits and the two score boards will reduce the number of I/O's required.

How big are the digits? For really big, like 3 or 6 LEDs/segment powered from 12V, then use strips if WS2812B can used with all digits as one big long string, or perhaps one string per digit, to allow multiple colors. If single color, than a shift register per digit can be used, with the data and clock shared among all digits.

(Youtube, look for cardinalflyer2011, I can't keep the smart-pasting here from screwing up the link)

I offer a basically ProMini-based board (off board FTDI used to load code) with up to 12 shift registers for driving up to 12 digits.
Here it is on accelerated count-up mode testing alarm clock function:

and here as a scoreboard with an RF receiver connected with a simple 4-button remote sending score up/down commands on two buttons, third used to increase period/quarter/inning (hockey periods in this case it looks like).
