Abstract:
We know technology is a blessing in our daily life. Technology is making our life easy to easier. A man cannot think without technology even for a single day. In this project, we have designed and developed an Arduino based Optical Mark Reader machine. We have used an Arduinouno Uno board and the main controlling unit and some other devices like- MUXs, switches, LM324 ICs and an Infrared based reflective sensor. The switches worked as answers from the OMR sheet & the MUX’s were used for selecting the switches and fetched them into the Arduino board. We also developed a program for proper functioning of the whole system using the Arduino-based software. The whole system has been designed and implemented properly. Finally the performance of the system has been studied and it is found that without some limitation of the sensor section the developed system works satisfactorily. It can read the answers of the OMR sheet with 100% accuracy.
