Laser emitter + receiver for Arduino (Arduino to Arduino communication) 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 &amp; 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?

Receiver: Laser Sensor Module non-modulator Tube Laser Receiver

Transmitter: 5V ... Board For Arduino AVR ... KY-008 Laser Transmitter

Looks like the receiver module has a low-pass filter. That could reduce the baud-rate depending on the RC-factor (10 Kohm * 10 nF gives a cut-off frequency of 1.6 kHz). I would recommend checking the actual components. The above is a guesstimate. 

Cheers!
