Connect boards through Serial communication)
Each of the 5 Uno's from the stepper motors needs to be connected to the finish Mega.

12Step 12
Program the horse boards to run the race that the mega sends it)
As mentioned above, the finish board will send a 5 digit code for the next race the horses should run. Break out that information and run the appropriate race.

At this time your horses should be running timed races.

13Step 13
Build an odds display)
Make a display 48" wide, and cut 10 square holes big enough for 2x16lcds for the odds, and 1 for the count-down clock.
![]()

14Step 14
Wire odds display)
I hooked the left 5 2x16lcds to one Mega, and the right 5 2x16lcds to another Mega. The countdown clock is hooked up to an Uno. All three board will need to be grounded to the other boards and hooked up to the serial communications to the Mega finish switch board.

Program odds display)
The board will receive the same 5 digit signal as the other boards, and break out the first two digits to print the odds.

The countdown clock also needs to have the common ground, and pin 13 (the backlight) is hooked also connected to pin 2 on the start Mega switch board.

17Step 17Build betting station)
The betting station needs to have 10 buttons, 10 7-segment leds with shift registers, and I have a LCD display on mine. If you plan on using it as a coin machine you will also need a coin in, and cash out. I have two versions of code: one for fun gaming with no coins and one for actual betting.
I will share the fun gaming version.
![]()
18Step 18Program the betting station)
The betting station needs to know the odds of the current race to know what to pay out if you win. It also needs to know the race winner.
Once again this is the fun version, so there is no code here for coin in, or cash out.
