I'm working on a project using 2 Arduinos connected to 2 computers to demo Serial to Serial communication.
We're using Arduino Uno connected to the computer via Serial and software serial for inter-Arduino communication. We used wires to connect software serial RX & TX lines, but we'd like to connect these pins to a laser transmitter and receiver.
We're trying to show wireless communication using an optical medium, which is why we wanted to use a Laser transmitter and receiver.
We're trying something like the setup in this YouTube video $3 laser transmits audio over 100m (Arduino)
Any idea how high a baud rate we will be able to achieve using the transmitter and receiver?
