A bionic arm will be one of the future biomedical devices which will help amputee people to increase their life quality. You are supposed to write a program for a bionic arm which is controlled by the patients eye movements using instructions below. (You are using Arduino Uno.) - Eye motions: Up: DI 3 HIGH Down: DI 4 HIGH Left: DI 5 HIGH Right: DI 6 HIGH Long Wink: DI 7 HIGH Double Wink: DI 8 HIGH Triple Wink: DI 9 HIGH

- Actions: Up: MOVE UP Down: MOVE DOWN Left: MOVE LEFT Right: MOVE RIGHT Long Wink: RELEASE OBJECT Double Wink: HOLD OBJECT Triple Wink: ACTIVATE ARM CONTROL (Remember position) - When USB asks for data by sending 1 to program it will return final status of the arm including all input states. - When no change on actions for 5 seconds, arm will automatically disable itself.
