The purpose of this project is to build and design an electronic communications system which is capable of sending and receiving audio signals within a limited area and connecting countable number of users. The main focus of my work has been towards the development of a circuit which can work as half duplex intercom under a unit box. This was achieved by designing an intercom on a Vero-board with 2 loud speakers and no microphone.
