Arduino "Blink To Talk" using Charlieplexing

This project can be classified as an AAC (Alternative and Augmentative Communication) device, which are used as a means of communication for those suffering from debilitating diseases like ALS and the like, that result in complete paralysis and near-total loss of body function. The device we shall build in the course of this instructable, enables a patient to communicate with people merely by blinking their eyes.”
