I am a beginner with Sabertooth and Arduino Uno Circuit.
I am having a tough time getting started and this seems kind of complex, nothing I have tried from Sabertooth and Arduino library has worked I did upload the blink test and that worked between the computer and the UNO but other than that I feel stuck.
We are running a Sabertooth 2x25 with Arduino Uno Board.
Our system is operated with a remote controller currently and we wanted to add the functionality option of autonomous.
So what we are trying to do is drive our system with remote control to a given location and then start the program.
Right now I have not even got the UNO circuit to even control the motors yet.
Can anyone help?
I uploaded programs but all seem to error out one way or the other.
Has anyone have the programs and code that works for the Saber tooth - UNO intergration?
Our system is a 350watt brush motor for forward and reverse on Channel 1 - S1 on the Sabertooth circuit
linear actuator controls left to right on channel 2 = S2 on sabertooth controller.
Thanks I appreciate any help I can get!
Right now I have not even got the UNO circuit to even control the motors yet.

I uploaded programs but all seem to error out one way or the other.
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?
For the standard remote control we have the dip switch setting on the Sabertooth at 2,3,6 are ON - 6 going on disables the microcontroller so I tried it at 2,3,5, ON
I ran the jolty program from the list of example programs and nothing...
I then unplugged the power to GND and 5V on the UNO and the system started moving the front wheels then the rear drive wheels took off wide open...
I turned it off and then on again and could get nothing ...

Sabertooth ST(128); // The Sabertooth is on address 128. We'll name its object ST.
// If you've set up your Sabertooth on a different address, of course change
// that here. For how to configure address, etc. see the DIP Switch Wizard for

// Be sure to select Packetized Serial Mode for use with this library.
//
// On that note, you can use this library for SyRen just as easily.
// The diff-drive commands (drive, turn) do not work on a SyRen, of course, but it will respond correctly
// if you command motor 1 to do something (ST.motor(1, ...)), just like a Sabertooth.
//
// In this sample, hardware serial TX connects to S1.
// See the SoftwareSerial example in 3.Advanced for how to use other pins.
void setup()
{
SabertoothTXPinSerial.begin(9600); // 9600 is the default baud rate for Sabertooth packet serial.
ST.autobaud(); // Send the autobaud command to the Sabertooth controller(s).
// NOTE: Not all Sabertooth controllers need this command.
// It doesn't hurt anything, but V2 controllers use an
// EEPROM setting (changeable with the function setBaudRate) to set
// the baud rate instead of detecting with autobaud.
//
// If you have a 2x12, 2x25 V2, 2x60 or SyRen 50, you can remove
// the autobaud line and save yourself two seconds of startup delay.
}
void loop()
{
ST.motor(1, 127); // Go forward at full power.
delay(2000); // Wait 2 seconds.
ST.motor(1, 0); // Stop.
delay(2000); // Wait 2 seconds.
ST.motor(1, -127); // Reverse at full power.
delay(2000); // Wait 2 seconds.
ST.motor(1, 0); // Stop.
delay(2000);
}
I did get this one to work so programming wise I will try to build off of it!

{

We have a functional program but noticed the distances vary in forward and reverse with a brush motor 350W - 24volt system.
Anyone ever run into a solution for that?
