hi guys!
just would like to ask help for our project proposal. Its a device whioch could electronically check test paper with answers in a shaded box form. We are planning to use a infrared circuits which could sense that a shaded portion exixt and convert it n digital form and compare it to the answer written by means a assemly program in the PIC. Can you give comments or any suggestion in doing our design. Or a working infrared circuits utizing reflective sensing. Thank you so much for those who are willing to help.
