Does anyone can explain to me what is slow or fast decay mode in DC Motor and how I can do it using my Arduino setup? Thanks
Electronics i used:
BTS7960 High power motor driver
Arduino Nano
550 Brushed Motor
RadioControl Transmitter and Receiver from a RC Car
That means acceleration or deceleration. How can we know anything about your Arduino setup?

Can you explain it further? Is it something that i can modify with my code to done that?
Sure, YOU can. We can't, you do know we can't see into your house?
Who can tell? How does your code make the motor go now? Is it from 0 to infinity in no time at all or does it go from to to some value over a time period you set?
Its goes from 0 to 255 base on your throttle input on your Radio Transmitter same goes with Reverse
The you will have to time delay the 0 to 255. Possibly 0 to 5 incremented by 1 every 100ms. Then 6-15, incremented every 50ms, then 16 to 200 every 10ms, then just 255.
Do the reverse when slowing down. Play with the both the time values and the steps.
Have you tried Google? The first result I got was:

It says basically the same thing I told you in your other post on the same subject:
The INH either connects or disconnects the OUT pin.
The IN determines if the OUT pin is connected to HIGH (+VS) or LOW (GND).
You need TWO BTS7960 drivers to control motor direction. The OUT of one goes to Motor+ and the OUT of the other goes to Motor-. Lets call their respective ve IN pins "IN1" and "IN2"
When INH is LOW, the motor coasts.
When INH is HIGH:
When IN1 and IN2 are both HIGH or both LOW, the motor is braking (the motor terminals are shorted together and the Back EMF is s…
Slow Decay = coasting
Fast Decay = braking
For posterity:
I think you made a minor mistake here.
Slow Decay = braking
Fast Decay = coasting
It's counterintuitive for sure, but remember the "decay" isn't talking about the motor speed, it's talking about the current flow.
