Project Discription

07-July-2018

Description: This is an Embedded system provide message communication without any wired requirement. Here Project can be used for various situtaion where user want to establish his personal communication channel. In this project liast of components have low cost. Attachment contain all required files.

Code Required for the control of the component is:
