Hi I have a project that I am attempting and I hope I can describe it well enough for you to understand. I would like to create something like a scoreboard display. I want to control a single digit display with with either 10 on-off switches or 1 10-way switch (If I can find one).
The display is going to be set up with regular incandescent lightbulbs 4 wide by 7 tall with 2 more across the middle to create a digital "8" figure. (20 total bulbs)
The only part I cannot figure out is how to easily and inexpensively be able to change the display from one number to another. Ex. First switch is on, display shows "0"; switch 1 off and switch 2 on, display shows "1" etc.
My first thought was to have the first switch display "0" when turned on by running positive current through that switch to the corresponding lightbulbs and then through a common negative wire among all the lightbulbs. The problem with that is that the 10 switches share some of the same lightbulbs and eventually each switch will just turn on all the lightbulbs because the positive wires coming from the switches would all be connected.
I hope this was easy to understand and I can post a picture in the future if needed. Any help would be appreciated. Thank you.
