RobotOpen Spike problems

[augusto.sk]

Hello, my name is Augusto and im a programming student from the team 383,

Im using an Arduino with Robot Open shield and im trying to control a spike. I turn it foward and stop, but i can`t turn backwards




if (estadoBtnA == true)
{
roleteOn = 1;
roleteOff = 0;

}

if (estadoBtnB == true)
{
roleteOn = 0;
roleteOff = 1;

}




if (roleteOn == 1)
{
analogWrite(SIDECAR_DIGITAL1, 255);
}


if (roleteOff == 1)
{
analogWrite(SIDECAR_DIGITAL1, 127);
}



Best regards!
Augusto
