Here is the data I am working from
http://www.dimensionengineering.com/software/SabertoothArduinoLibrary/html/index.html
Page 4 is very similar to our setup we use 24v and 1 brush motor 350w for forward and reverse and a linear actuator motor for front steering.
I actually had some motors working for a brief period? I think it might have been the driving in a square example program. I will try uploading it again to see if I can get it to work again.
I changed the program on the UNO then it did not work. I wish I would have remembered what program that is was to have it work again!
It worked with a set of jumper wires to (UNO board)port 9 fpor S1 (sabertooth 2x25)and (Uno board)port 10 to S2 (sabertooth 2x25)
On sabertooth board I had 0V and 5V hooked up to UNO to supply power on UNO board to GND and 5V slots.
On the sabertooth dip switch I had it set to 2,3,5 ON all others off....
When we operate the remote controller to manual drive it over to the desired start position we need a way to shut off UNO while doing that?
