Quick start simtools need help

Hello,
I build simulator with an arduino and simtools and i read the quickstart but i have a problems.
I read the part : d) ARDUINO Game Engine interface settings for configure the communication into arduino and the computer. The communication is ok but when i try "moving simulator with mouse " there is no voltage on the arduino's output. I test particulary the PWM output same problems.
In the quickstart there is no question about code for arduino. Is needed to send source code in the arduino ? for initialise communication ?
I try to found code and extract what i need:

void setup()
{
// serial initialization
Serial.begin(115200);

// initialization of Arduino's pins
pinMode(statpin, OUTPUT); //not explained by Sparkfun
digitalWrite(statpin, LOW);

but it's not work.
I'm novice in programming that the big problems.

Thanks for help and reply.
Very Sorry for my bad english i try my best.

Hello!
What is your hardware setup? Hbridge ?
How far is your knowledge of Arduino?

The Quick guide do let you choose anything you want : JRK, SCN, Arduino (Prilad code, RufusDufus code, mine...)

Depending on Ard code you are using , follow their post where the Ard code came from not the Quick Start mate.

Thanks for reply.
First time with arduino so for the knowledge ... ^^.
For the arduino code i get the racingmat code but it's so big i just need the necessary for communication.

Simple Serial read is easy with the Ard , I can show you a quick example if needed, I do this with my RC Model code plus the 3 dashboard codes I wrote and use.
