Description
Social networks are a recent phenomenon of communication, with a high prevalence of young users. This concept
serves as a motto for a multidisciplinary project, which aims to create a simple communication network, using
light as the transmission medium. Mixed team, composed by students from secondary and higher education
schools, are partners on the development of an optical transceiver. A LED lamp array and a small photodiode
are the optical transmitter and receiver, respectively. Using several transceivers aligned with each other, this
con guration creates a ring communication network, enabling the exchange of messages between users. Through
this project, some concepts addressed in physics classes from secondary schools (e.g. photoelectric phenomena
and the properties of light) are experimentally veri ed and used to communicate, in a classroom or a laboratory.
