The projects main contribution the VLC field is the addition of networking technology.
The web link driver interfaces between IP protocols and the VLC layers.
The Linux controller module communicates with the Arduino-based firmware module using a serial interface.
The Arduino module then directly drives the LED and sensors.
The above images show the insights of the Linux Light Bulb.
The Atheros chips in the Linux Light Bulbs have built-in WiFi, which Disney Research used for testing purposes.
Yet, the lights are intended to communicate with each other only using VLC, notes the Disney paper.
By adding networking to VLC, Disney has apparently overcome the technologys major limitations of range and signal interference.
Advantages over wireless communications not only include lower cost and power consumption, but also better security.
Disney Research envisions the technology as extending beyond the next generation of Disney toys to other low-bandwidth IoT applications.
A wider role for light communications may await future processors that incorporate so-called III-V materials.
