[menji]

hi everyone, i'm having a really hard time right now. i follow everything from this figure, but still, my motor wont work. only my hc05 is successfully connected to the phone. i only changed the battery where i changed it to six 2A battery resulting 7.5V, but the motor still not working. can someone help me? Thanks!!!

Please post code, the proper way using code tags, post a wiring diagram, not a wall painting.

and links to motors, driver board.

sorry sir. ok here u go

and this is the coding that i used.
#include "AFMotor.h"

int MOTOR_1 = 1;
int MOTOR_2 = 2;
int MOTOR_3 = 3;
int MOTOR_4 = 4;

AF_DCMotor motor1(MOTOR_1, MOTOR12_64KHZ); // create motor object, 64KHz pwm
AF_DCMotor motor2(MOTOR_2, MOTOR12_64KHZ); // create motor object, 64KHz pwm
AF_DCMotor motor3(MOTOR_3, MOTOR12_64KHZ); // create motor object, 64KHz pwm
AF_DCMotor motor4(MOTOR_4, MOTOR12_64KHZ); // create motor object, 64KHz pwm

int state;
int Speed = 130;

void setup() {
motor1.setSpeed(Speed); // set the motor speed to 0-255
motor2.setSpeed(Speed);
motor3.setSpeed(Speed);
motor4.setSpeed(Speed);
Serial.begin(9600);
delay(500);
}

void loop(){
if(Serial.available() > 0){ //if some date is sent, reads it and saves in state
state = Serial.read();
if(state > 10){Speed = state;}
}

motor1.setSpeed(Speed); // set the motor speed to 0-255
motor2.setSpeed(Speed);
motor3.setSpeed(Speed);
motor4.setSpeed(Speed);

delay(80);
}

void forword(){
motor1.run(FORWARD); // turn it on going forward
motor2.run(FORWARD);
motor3.run(FORWARD);
motor4.run(FORWARD);
}

void backword(){
motor1.run(BACKWARD); // the other way
motor2.run(BACKWARD);
motor3.run(BACKWARD);
motor4.run(BACKWARD);
}

void turnRight(){
motor1.run(FORWARD); // the other right
motor2.run(FORWARD);
motor3.run(BACKWARD);
motor4.run(BACKWARD);
}

void turnLeft(){
motor1.run(BACKWARD); // turn it on going left
motor2.run(BACKWARD);
motor3.run(FORWARD);
motor4.run(FORWARD);
}

void Stop(){
motor1.run(RELEASE); // stopped
motor2.run(RELEASE);
motor3.run(RELEASE);
motor4.run(RELEASE);
}

It tells how to post code the right way using code tags.
Post a proper wiring diagram.
I don't find any links to data sheets for motors, driver board etc..

64kHz PWM is far too fast for L293D chips I fear. Try MOTOR12_8KHZ for motors 1 and 2,
and MOTOR34_8KHZ for motors 3 and 4.
