@ DJ or anyone else:
I need some clarification on the hook ups for the L298N, if you please. DJ, you answered my first question about this motor driver in my original post. I understand the IN1, IN2, IN3, IN4. To digital "trigger" pins;( like: D1,D2,D3,D4). Its the PWM I a bit confused on. In your first answer you said "connect "one" pin assigned to a digital port,PWM, trigger (like D19 for instance)" and connect that to one "enable" pin (like ENA) and that one PWM would control both enable pins.
I then watched your video tutorial on PWM and in that video I see you connected "four" pins to the enable pin outs. (So I presume they are connected to ENA, +5, +5, ENB ??) and then these were connected to four digital trigger pins (like D19, D18, D17, D16). See why I'm a bit confused? I've attached another pic of the L298N I have, just for clarification.
Thanks in advance.
