I am trying to drive a 6V DC motor with an L293D driver and ATmega8 without PWM. The problem is that, I am getting a very low speed while connecting the motor via the L293DL293D driver.But, It rotates well when I provide a direct 6V DC supply to the motor.

I am using an external 6V source at the VS (motor supply) pin of the L293D but there is no improvement. The motor does not rotate until I turn the rotor by hand. What could be the problem? My code is here:

DDRB = 0xFF;
while(1)
{
  PORTB = 0B00000010;
  _delay_ms(20000);
}

DC motor speed is too low while interfacing with L293D motor Driverdriver and Atmega8ATmega8

I am trying to drive a 6v dc6V DC motor with an L293D driver and Atmega8ATmega8 without PWM. The problem is ithat I am getting a very low speed while connecting the motor with L293Dvia the L293D driver. But, itIt rotates well when iI provide a direct 6V dcDC supply to the motor.

I am using an external 6v6V source at the VS (motor supply) pin of the L293D, but there is no improvement. The motor does not rotate until iI turn the rotor withby hand. What could be the problem? My code is here:
