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:
