Each menu has few submenus and also their sub-child which call various function to perform related task for clear understanding see below pictures. Followings are the software required to make this project. 1. Proteus for simulation of arduino hex file. Note:- how to simulate hex file in arduino please see how-to-make-quick pressed led 2. Arduino for coding. Now Visit the given drive to get all the files. For any queries comment below. Thank You
