4 digit 12volt Horseshoe scoreboard

kingspud · 2008-04-30 05:04

Hello all,

Well I finally completed the code for my 12volt 4-digit seven segment display horseshoe scoreboard!

The scoreboard uses 6 momentary switches:

player 1· UP/DOWN switches
player 2· UP/DOWN switches
a switch that lights an arrow that points at player 1 or player 2
and a reset button.

There are two separate two digit displays for each players score that goes to 25.· It could go higher but you would have to enter all the digit codes to increse the digits to 99!·

The components:

BS2p40 = 1
4511 -·BCD to digit chip = 4
UDN2981 - 8 channel source driver chip = 4
two 7905 regulator chips
12volt power supply
assorted connectors for ribbon·cables

All chips·used·chip sockets for easy replacement.

I will include photos when I have the case made!

I used the Proteus 7 simulation software for simulate the code.

Wonderful! The topic says 16 volts, something you may want to remove [noparse];)[/noparse]
At a quick glance, you should be able to save a bunch of memory by making a LOOKUP subroutine. It may not work
