Sweep motion with Adafruit motor shield and Dc motor with encoder

help needed

my goal control dc motor , gearbox rotary encoder sweep left right repeating
here's basis of goal not work 

code: [select]

while (myenc.read() < 50)   {
motor.run(forward);
}
while (myenc.read() >50)    {
motor.run(backward);
}



what motor doing isn't wanted?

your range of swing set low since reverses direction in range 49 51.  have thought of using wider range, <45 , >55?
