Defect Detector – Big Picture

The purpose of our final project was to build a device where a user could place an object into a box to be sorted. The pressure sensor embedded between two plates is designed to give an analog voltage output. The raw voltage obtained from the pressure sensor is converted by an analog to digital converter (ADC) on our A3BU board, and given a digital value between 0 and 127. The plate was controlled by a servo motor which could rotate to three positions; left, center, and right.
