Upgrading old sewing machine with Arduino control

Andrew has an old sewing machine that does great job, but has only couple features like straight and basic zigzag. So he thought it would be fun to incorporate Arduino and servo motor to enhance its functionality.

So he ended with CNC sewing machine which can work in several modes. First of all it duplicates previous options so it would work as previously. Then it can sew with one of 10 preset patterns that are stored in Arduino memory. And lastly it can accept new patterns via USB interface. Servo motor is nicely integrated in to sewing machine which simply drives needle horizontal position. Needle bar is equipped with sensor so Arduino could know when its in full-up position. Project is still in development phase so hopefully we will see some clever sewing that include letters and some basic graphics.
