Bluetooth motor control./Serial communication

Using Arduino Programming Questions
#1

I am working on a project involving controlling motor via Bluetooth, I have achieved control but what I’m seeing is that when I send the value that translates to forward it keeps moving after I release the button, I’m new to serial communication I suppose my real question is how do I have a constantly updated stream as opposed to the Arduino saving the state until it is changed? Thanks in advance.

It looks to me as if your code will constantly update itself everytime something is received.

What is it actually doing that you don't want to happen?

I wonder is the problem that it receives a different character when you release the button? If so have your code ignore that character.
