Test sheet Correction using microcontroller

Abstract

The aim of the project is to build an embedded system to help teachers in correcting exam papers in a high accurate process. This system can be used in the elections and questionnaires to obtain information with high accuracy. This project will use the Nano Arduino microcontroller for correction of exams. The process will start by read shaded choices using a color sensor. After comparing the answer with the typical answer from the admin, the result will be displayed on PC monitor connected to the microcontroller with a notification if needed if there is any error.
