Need Help In Arduino Uno, L298N and Dc Motor

Using Arduino Motors, Mechanics, Power and CNC

I cant seem to be able to attach as i think the circuit file is large but i have done that and even connected 5v motor driver to arduino vin

The 3 left pins on the driver header are needed for the A motor to work.

EDIT
The Arduino pin 10 wire is not needed.

You need Motor 1 enable, IN1 AND IN2 connected to appropriate Arduino pins.

That battery is too feeble for the job and won't last long at all. A set of AAs connected to give you an appropriate voltage for your motor (plus driver loss) will do better.

What should i put on in2

30

Where can I get those? please send me a link ( not on amazon as i cant order from there) if you can find one on flipkart as it delivers to My Country

31

While i was replying i noticed that the motor had stooped rotation from 1 rotation per 10 min to 1 rotation per 3 min. What could be reason behind this

32

You need Motor 1 enable, IN1 AND IN2 connected to appropriate Arduino pins.

33

how to do it please tell

34

uh... i cant buy from amazon...pls search something on https://www.flipkart.com/ as i bought my arduino and motor driver there

Thanks Ill check it out. Please tell me what to do of IN2

37

Make sure you get a battery holder that holds 8 AA batteries.

38

Let’s see your current sketch.

39

Please see post no 28

40

should i buy this?

41

For experimenting just use the battery holder and 8 AA alkaline batteries.

42

ok. i am sending code,only difference in wiring is that i have connected IN2 to the corresponding pin in the code

int Xpin = A0;
int Ypin = A1;
int Xval;
int Yval;
int m1Pin1 = 2;
int m1Pin2 = 3;
int m2Pin1 = 4;
int m2Pin2 = 5;
int m1SpeedPin = 9;
int m2SpeedPin = 10;
int m1Speed;
int m2Speed;

void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  pinMode(Xpin, INPUT);
  pinMode(Ypin, INPUT);
  pinMode(m1Pin1, OUTPUT);
  pinMode(m2Pin1, OUTPUT);
  pinMode(m1SpeedPin, OUTPUT);
  pinMode(m2SpeedPin, OUTPUT);
  digitalWrite(m1Pin1, HIGH);
  digitalWrite(m2Pin2, LOW);
  digitalWrite(m2Pin1, HIGH);
}

void loop() {
  // put your main code here, to run repeatedly:
  Xval = analogRead(Xpin);
  Yval = analogRead(Ypin);
  m1Speed = map(Xval, 0, 1023, 0, 255);
  m2Speed = map(Xval, 0, 1023, 0, 255);
  analogWrite(m1SpeedPin, m1Speed);
  analogWrite(m2SpeedPin, m2Speed);

  if (Yval < 470 )
  {
    m1Speed = 0;
  } else if (Yval > 550) {
    m2Speed = 0;
  } else {
    m1Speed = map(Xval, 0, 1023, 0, 255);
    m2Speed = map(Xval, 0, 1023, 0, 255);
    analogWrite(m1SpeedPin, m1Speed);
    analogWrite(m2SpeedPin, m2Speed);
  }


  delay(100);
  Serial.print(" m1spped = ");
  Serial.print(m1Speed);
  Serial.print(" m2speeed = ");
  Serial.println(m2Speed);
  delay(1000);
}
