Hi
Few Days back I brought an FreeDuino (ARDUINO) board ATMEGA 328P
I manage to Move MY first Assembled CAR with the free codes online (https://www.sparkfun.com/products/9457) (http://bildr.org/2012/04/tb6612fng-arduino/)
but I am not using this Motor Driver (1A Dual TB6612FNG) but using L293D Motor Driver

I would like to move it Forward then Right-Forward , Left-Forward , Reverse Then Right-Reverse , Left Reverse or any other direction but it should come back to its Original PLACE from where it STARTED.

//motor A connected between A01 and A02
//motor B connected between B01 and B02

int STBY = 10; //standby

//Motor A
int PWMA = 3; //Speed control 
int AIN1 = 9; //Direction
int AIN2 = 8; //Direction

//Motor B
int PWMB = 5; //Speed control
int BIN1 = 11; //Direction
int BIN2 = 12; //Direction

void setup(){
  pinMode(STBY, OUTPUT);

  pinMode(PWMA, OUTPUT);
  pinMode(AIN1, OUTPUT);
  pinMode(AIN2, OUTPUT);

  pinMode(PWMB, OUTPUT);
  pinMode(BIN1, OUTPUT);
  pinMode(BIN2, OUTPUT);
}

void loop(){
  move(1, 255, 1); //motor 1, full speed, left
  move(2, 255, 1); //motor 2, full speed, left

  delay(1000); //go for 1 second
  stop(); //stop
  delay(250); //hold for 250ms until move again

  move(1, 128, 0); //motor 1, half speed, right
  move(2, 128, 0); //motor 2, half speed, right

  delay(1000);
  stop();
  delay(250);
}

void move(int motor, int speed, int direction){
//Move specific motor at speed and direction
//motor: 0 for B 1 for A
//speed: 0 is off, and 255 is full speed
//direction: 0 clockwise, 1 counter-clockwise

  digitalWrite(STBY, HIGH); //disable standby

  boolean inPin1 = LOW;
  boolean inPin2 = HIGH;

  if(direction == 1){
    inPin1 = HIGH;
    inPin2 = LOW;
  }

  if(motor == 1){
    digitalWrite(AIN1, inPin1);
    digitalWrite(AIN2, inPin2);
    analogWrite(PWMA, speed);
  }else{
    digitalWrite(BIN1, inPin1);
    digitalWrite(BIN2, inPin2);
    analogWrite(PWMB, speed);
  }
}

void stop(){
//enable standby  
  digitalWrite(STBY, LOW);
}

I have 2 DC Gears Motors on a cheese on pin 8,9 ,11 & 12
with FREEDUINO Board

But don't know what to do with pin no 3 & 5 ??? & pin no 10 ???
which is for Speed control & standby respectively ..


can any one guide me how to code for the above requirement
Thanks in advance

 

You can hook those to the en pins of the L293 The L293 can be used
the same way as the one the code was made for

 

Thanks
be80be for your ans.
you mean to say that the pin no 3 & 5 of the ARDUINO to pin no 1 & 9 to the L 293 respectively & pin no 10 ???
which is for standby .....
