This is the code to control 2 motors with a Bluetooth module the problem is that when the Serial receives a letter, let's say "s" it stays inside the loop forever and the motors keep on moving, what I want is that when the Bluetooth serial communication I want my motors to move just when the "s" is being kept pressed, like a push button or a remote control. Do you have any solutinos that worked for you? Suggestions on what to try?
Thanks in advance!

AnalogReadSerial
Reads an analog input on pin 0, prints the result to the serial monitor.
Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.
