Assemby program code for Automatic Door Opening System (8051 family microcontroller)

This assembly coded to run automatic door opening and closing system. It has infra-red (IR) Sensors to detect proximity approach of object. This input is used to control opening and closing motor system with appropriate delay. Mostly, slide door is used for this purpose, however, any other type can also be operated.

Reply 17:41 2020-06-10

Mahesh Nigam(Scientist): Don't used assembly code, it may arise lots of error due to dependent codes that was includes with this source code. Use hex code. It is used by many people and working correctly.

Jeorge Ban: Mr. Mahesh i need your help sir!!! actually i need and assembly code for automatic door opener as example and i need it to be worked in visual c++ 2010 express, if u can provide me one or at least give me any resources that may be helpful for my project, because we don't do it in actual, we just need one example for our semester project to provide an assembly code from visual c++ express 2010... THANKS!
