I am new to these Arduino things, and I am currently using an Uno board for my projects.
I don't know how to control the DC motor with the help of digital pins via L293D. But I cannot use the PWM pins of Arduino, since I have already used them for controlling servos and other things, which need higher accuracy.
I tried using the SoftPWM library to control motor, but it is conflicting with other things like ultrasonic sensor. I don't know what the problem is.
Could someone suggest me a solution?
