I’m using L293D with two DC 5V motors. I use the two ENABLE inputs feeding from two PWM inputs.PWM frequency = 200Hz.
L293D power from 5V supply.Vcc2 = 6V for motors in L293D.
The problem is I can speed down the motor very few range from PWM signal.
I use 8 bit resolution.
so the maximum speed = 255 duty cycle = 5V
The low range is only 180 duty cycle = 3.5V (not noticeable much)
Below 180 duty cycle the motors won’t work. But the motors will work down to 1V direct power supply.
I guess the enable pin does it have a threshold value??
