wireless notice board

Description

The main objective of this kit wireless notice board is to design a system with the help of which we can display the data on a display device by writing the data on a PC. The interface is should be easy so that a layperson can also use the system effectively. Although there is no limitation of features of the interface, we will focus on sending data from the computer to the device wirelessly.

This wireless notice board kit has two sections of the system, one is the transmitter and another one is the receiver. The transmitter is connected directly with the computer and the receiver can be moved anywhere in the range. The interface can be designed using any language as per requirements. The interfacing is based on UART standards.

In the kit wireless notice board, the UART port is found in microcontrollers but unfortunately, it is not there in personal computers. Hence we have used a USB to UART converter to convert the USB data into UART and this way the interfacing is done between computer and microcontroller. The use will type the data in PC which will send via USB port to the microcontroller and the microcontroller will display the data on LCD. The data sent will also scroll on LCD. The device can be either USB powered or it can be connected with an external power supply also.
