Hello,
I am trying to change the speed of a small dc motor using the module L298N and Arduino UNO. I am using the enable pin (Which is the pwm pin of L298N) in order to change the speed of the dc motor. The value of that pin must vary from 0 to 255 and the problem is that the constant value is from 0 to 1. When I set the constant >=0.5 motor starts at full speed and when I set it <0.5 motor stops. This means that it can understand only 2 states (on and off), is there any way to make it control its speed?
Thanks for your time, appreciate your help.

The L298N does not do its own PWM. The enable pin only supports two states. In order to modulate the driver current, you need to actually apply a PWM signal.
