Abstract
The project Simple Messenger development without internet is a very simple project which can replace the existing chatting systems. Chatting systems are very much important and play a crucial role in present day lives. Most of the users use these chatting systems for data exchange. But sometimes they feel inconvenient due to the problems occurring during chatting. To avoid this, Simple messenger development system has been designed.
The most efficient and reliable wireless communication is RF. The RF modules used here are 2.4GHz UART. The data entered from the PC keyboard is sent to the microcontroller at the transmitter side. The microcontroller passes this data to the RF transmitter through RF Encoder.
At the receiver end, the RF receiver receives the data from air, passes the data to the microcontroller. This microcontroller receives this data and just displays it on the receiver PC. Thus, communication between two systems can be carried out smoothly without any hardwired connections.
