What about the newer Arduino Leonardo ?

This board based on Atmega32u4 chip ( this chip has onboard USB controller ). This chip is not compatible to Atmega328, and this firmware can't work on Arduino Leonardo.

As asked here is the wiring guide for connecting a Freetronics UNO or a real UNO to Sparkfuns Monster Motor Driver.

I strongly recommend connect Monsters +5V to OTHER power supply. Do not connect +5V line and GND line from Arduino to Sparkfun MM Driver.

You can see at the topic page Connecting Diagram with SEPARATE supplies +U1(5V) and +U2(5V) and GND_USB and GND_PWR

I placed firmware files for Arduino UNO to the topic.

Hi guys.
Hi BobBuilt.

Yesterday my friend tested ALL Arduino UNO firmwares on his ard board (with Atmega8u2). And he got good communicate on 57600 baud without any troubles. He has Win XP. And every time after uploading firmware to Arduino he reconnected USB cable to PC. This is inportant.

Can you check this on you Ard?

Update: Confirmation firmware 57600 for uno works perfectly if you unplug uno after flashing and plug it back in before starting program. All good thanks Prilad.

Ok. I updated topic with this information

Hi prilad,

I realized that may be my board have 2 opto isolators for 2 motors . But I do not understand where to connect VCC & GND to it ?

Might you check it for me, pls ?

(Sorry I can not sent you link of motor driver because that website does not have English )

Yes, your board has opto-isolators. Not necessary to connect VCC to this board. All pins Dir and PWM marked as (-) you must to connect to GND_USB in microcontroller board (not to GND_POWER).

wow, hear you say I am so happy , so things will be easier for me to built my simulator . So I'll buy arduino uno and built it now ...

Can you please help me to connect the UNO to Sabertooth 2x25 Motrodriver?
The Sabertooth have only S1 S2 5V and ground
And which mode should i use for the Sabertooth? R/C , analog,serial??

Thx Menix
