This project initialize the digital communication using the visible light and that must be reliable ,So it must be secured , less expensive and ecofriendly .The proposed system with following devices in transmitting section using pic16f877a microcontroller along with this a high bright led light is used as the medium of transmission the transistor Bc547 is used along the led light for switching 5v to 12v.when an data is given to the PC micro controller starts to read the data and then it converts the normal data into the binary data that is the data is encrypted then it passes as digital pulse into the led. The led starts flickering the data will transmit on the receiver the photo diode starts to detect the light and generates the electric pulse these pulse will reach the amplifier for processing and then the processed data is reach the Arduino the data is visible on the serial monitor of the Arduino IDE. The line of sight is more important in this transmission, which is more important but there is interference with other light darkroom is better result.
