Using Light Sensor of Mobile to Read Information From LED.
INTRODUCTION: Sending information from inside electronic gadget can be done through LED bulb. Reading the data in this case can be by photo sensor device. As the mobile is commonly used, using the light sensor of a mobile is targeted in this project. data through illumination
The technique behind is by using LED light bulb's output to fluctuate at high speeds. If the LED is switched on then the data transmitted is a digital one and if the LED is switched off, then the data transmitted is zero. This fluctuation of the LED light is detectable by Photo-detector.
The LED light bulb used to transmit the data controlled by a microcontroller. This microcontroller switching the LED light converts the digital data to light waves which are then transmitted. These transmitted waves are received at the receiving end by a photodetector, which is then amplified, decoded and converted back to its original format. This message is then transmitted to the end receiver which can either be a mobile device or a computer.
We would like to use light sensor of the mobile device to convert the fluctuation in the LED light into an image consists of dark band represent the data bit zero and the light band represent the data bit one.
REQUIREMENT:Mobile application software for reading data transmitted through LED bulb, received by light sensor of a mobile, and to display on the mobile screen
