L298

 Introduction :

The Motor Driver is a module for motors that allows you to control the working speed and direction of two motors simultaneously .This Motor Driver is designed and developed based on L298D

• Operating voltage range: +5 to +46V
• Maximum supply voltage:50V
• Maximum Input and Enable Voltage:+7V
• Maximum current allowed to draw through each output: 3A
• TTL control inputs
• Total power dissipation:25W
• Operating temperature: -23°C  to 130°C
• Storage Temperature: -40°C  to 150°C   

2.code arduino (exp 1):










int in1= 2;    // Forward for motor A (left)


int in2 = 3;    // Reverse for motor A (Left)


int ENA = 9;  // Turns motor A on/off





int in3 = 4;    // Forward for motor B (Right)


int in4 = 5;    // Reverse for motor B (Right)


int ENB = 10; // Turns motor B on/off








void setup()


{


   pinMode( in1, OUTPUT );   


   pinMode( in2, OUTPUT );


   pinMode( ENA, OUTPUT );


   pinMode( in3, OUTPUT );   


   pinMode( in4, OUTPUT );  


   pinMode( ENB, OUTPUT );


}





void loop()


{


   digitalWrite( ENA, HIGH ); 


   digitalWrite( in1, HIGH );    


   digitalWrite( in2, LOW );    





   digitalWrite( ENB, HIGH ); 


   digitalWrite( in3, HIGH );    


   digitalWrite( in4, LOW );     



}

INPUTS	FUNCTION
Q1=HIGH, Q2=LOW	Forward current
Q1=LOW,Q2=HIGH	Reverse current
Q1=Q2	stop

     4. code arduino l298 (exp2 ):

const int Q1= 8;    
const int Q2  = 9;  

int EN1 = 11;   

   void setup()

{
  
    pinMode(EN1, OUTPUT);   
    pinMode(Q1, OUTPUT);
    pinMode(Q2, OUTPUT);
   
  
}

void loop()

{
    sens1();

    sens2();

    stopp(); 

 }

void sens1(){

        analogWrite(EN1,255 );//sets the motors speed

        digitalWrite(Q1, HIGH);
        digitalWrite(Q2, LOW);}

void sens2(){

        analogWrite(EN1,255 );//sets the motors speed

        digitalWrite(Q1, LOW);
        digitalWrite(Q2, HIGH);}

void stopp(){

        analogWrite(EN1,0);//sets the motors speed

        digitalWrite(Q1, LOW);
        digitalWrite(Q2, LOW);}
