摘要：

The growing and continuous evolution of communication around the world, mainly due to the Internet of Things, has brought new perspectives on techniques for exchanging data. Visible Light Communication (VLC), a technology that uses Light-Emitting-Diodes (LEDs) modulation to send data, has become an alternative to radiofrequency, since its bandwidth is becoming scarce. This article proposes a didactic application of VLC using low-cost embedded systems, like off-the-shelf components and two Arduinos UNO. In addition, this application features On-Off Keying (OOK) modulation and Manchester Code as techniques for sending data and calculating the checksum for verifying the message correctness. In this approach, we reach a communication rate of 500 bps, at a distance of 40 cm. In addition, all hardware design e software code were provided.
