Abstract
Currently, WiFi technology is used worldwide for wireless communication. Despite its wide
use, WiFi has some conditions that are intended to improve, such as security, interference
with other radio frequency (RF) signals and bandwidth. Recently, Visible Light
Communication (VLC) has become an alternative to WiFi. This work addresses the
implementation of a communication system with visible light, using pulse-amplitude
modulation (PAM) and a PIN photodiode-based receiver, as a device for data interface a
32-bit microcontroller and in conjunction with a graphical interface of HTerm software. It is
proposed to implement a functional prototype that transmits and receives modulated /
demodulated information using OFDM through a PIN photodiode, which achieves transfer
rates in the order of Kbps.
