DualMotorDriver

Library to use dual H-bridge motor drivers (L293D or similar) for bi-directional PWM-control of two DC-motors

Notes

Increase PWM-frequency for better control and less noise

In your arduino setup()-function, make the PWM on Timer 1 faster by changing the timer prescaler from 64 to 1 with the following two lines. The PWM frequency will then be about 60kHz

TCCR0A = _BV(COM0A1) | _BV(COM0B1) | _BV(WGM01) | _BV(WGM00); 
TCCR0B = _BV(CS00); 

You need to be carful because this messes with millis(), micros() and delay() You might want to define custom function such as

unsigned long myMicros()
{
	return micros()/64;
}
