Toys communicating with LEDs: Enabling toy cars interaction

Communication capabilities are becoming a popular feature for premium smart toys. However, the higher cost of such transmitters are limiting the widespread use to all consumer users. In this contribution, we demonstrate a cost-effective toy communication using LED-based visible light communication (VLC), where messages sent via VLC are i) displayed on a screen, or ii) passed from one node (like a car) to another in a multi-hop way.
