<h3 >Introduction</h3><p >Networking is the one the most effective mode and medium of Intra communication technique which is used to communicate the people connected into the Intranet. But chatting with your colleague is possible with using Arduino? Yeah. Of course possible. Today we are going to discuss about it.</p><h3 >Hardware Required</h3><ul ><li >Arduino mC x2</li></ul><ul ><li >HC-05 BT module x2 </li></ul><ul ><li >Serial Communication cable x2</li></ul><ul ><li >Hookups x8 </li></ul><ul ><li >PC (Laptop or Desktop) x2     </li></ul><figure><img src=https://projects.arduinocontent.cc/8d331ac8-8645-4152-badc-115663fb0762.jpg /><figcaption> </figcaption></figure><h3 >Software Required</h3><ul ><li >Arduino IDE    </li></ul><p >Arduino IDE is an Integrated Development software to edit, debug and run your Embedded C program.
