Hi!I try make sumo robot and line following robot together.I have write code,but if i run it in my my robot has difficulty doing the drive I have written on arduino idle. I use arduino uno,breadboard,L239d,2 dc motor,9v batteryultrasonic sensor hc-sr04,2 qre113 analod,1 switch on off and some cables.My code have any problem?How i can add code about line following robot in sumo's arduion code,?

My code have any problem?
That is something you need to tell us. What does the code ACTUALLY do? How does that differ from what you want it to do, if it differs at all?

Code: [Select]
void Stop(){
 
   
 
    digitalWrite(I1, LOW);
    digitalWrite(I2, LOW);
    digitalWrite(I3, LOW);
    digitalWrite(I4, LOW);
  Serial.println(" stamata");
  //delay(2000);
}

It pisses my off royally when someone jams the { up against the function





and then wastes space with a bunch of blank lines. Get rid of the useless blank lines. Put EVERY { on a line BY ITSELF. Put EVERY } on a line BY ITSELF. Use Tools + Auto Format to properly indent the code.

Code: [Select]
ROTATE(); // start roteteint QRE_Serial.print("xroma ");



 if (distance < 10){
    Stop();

Unconditionally rotate. Then, depending on distance, do something, which might, or might not, include reading some undefined sensor. That hardly makes for a well controlled robot.
The art of getting good answers lies in asking good questions.
