L298 dual h bridge driver not driving DC motor

Hi

I have L298 dual h bridge driver connected to a DC motor

Motor and and battery ( 11.1 V LiPo ) are connected as follows

Battery + terminal = VCC on driver
Battery - terminal = GND on driver + GND on Arduino

ENA = pin 3
IN1 = pin 8
IN2 = pin 9

Arduino code (obtained from driver's company) :

/* L298N DC motor example */

int IN1=8;
int IN2=9;
int ENA=3;
void setup()
{
 pinMode(IN1,OUTPUT);
 pinMode(IN2,OUTPUT);  
}
void loop()
{  
 analogWrite(ENA, 200);// motor speed  
 digitalWrite(IN1,LOW);// rotate forward
 digitalWrite(IN2,HIGH);
 delay(2000);  
 digitalWrite(IN1,HIGH);// rotate reverse
 digitalWrite(IN2,LOW);
 delay(2000);
}

Driver has a red light on but the motor does not move

Any ideas why would this happen ?

Have you got the jumper on or otherwise supplying 5V to the 298 logic?

edit: oh wait, the red led means there's 5V present I think.

Have you put the motor straight on the battery to test it's ok?

Yes. The motor runs perfectly when hooked up directly to battery

That motor is a high power RC motor, an L298 is way too low current for it.

Ok so it seems that pins on the arduino was flipped

I got a smaller motor to work

but when I hook the big one it keeps beebing

is this due to the low current ?

Is there still a way to use this driver for a high power motor ?

Im getting this error too! I am using this H-bridge to control two motors using a potentiometer. When I run i, there is a red light that shines and the motor barely runs it and rather beeps instead of runinng.

Ask the same question you'll get the same answer but in capitals.

so it wont work at all?

@MarkT, don't shout too much at inhabani, it's Bull Engineer necro-ing this thread asking pretty much the same question that he (BE) has been asking all over :wink:

You simply didn't setup the ENA pin as an OUTPUT, duh

AyaAj:
You simply didn't setup the ENA pin as an OUTPUT, duh

And you, AyaAj, simply didn't rtfm:

You do not need to call pinMode() to set the pin as an output before calling analogWrite().

analogWrite(ENA, 200);// motor speed

So you might like to retract that "duh"?
