John Schmitt / Mbed 2 deprecated limb2

Move a limb and read its position with a flex sensor.

Dependencies:   C12832_lcd LCD_fonts Servo USBDevice mbed

I wanted to create the simplest limb as part of a course. It involves a limb that moves driven by a stepper motor. The angle of the limb is read by using a flex sensor.

The first time it worked:
