Bluetooth Based LED Notice Board Electronics Engineering Final Year Project

This project includes Bluetooth (HC-05) module, which is connected to Arduino through UART interface. LED notice board connected to Arduino UART.

WORKING:

In this project we can interface LED display to Arduino. LED display has UART provision and we can edit data from UART port. Arduino sends commands and data to UART port. It has android app with text box facility. In textbox user can give data which he wants to scroll on LED display. Arduino get the data from Bluetooth and send to LED board. LED board displays data along with date and time.
