I am interested in sending Data from a PC to another PC or Arduino to Arduino via a laser.
I found this video that shows how it is done but no code/schematic.
Has anyone found a more detailed example with schematic and code?
I will try this weekened to reproduce what I have seen in the video but if someone knows of a tutorial that does this already it would help me a lot.
cheers

I've sent audio wirelessly by modulating a laser pointer. Below were my references:
These were used for analog signals so they used a transformer...digital should be easier i think. Maybe you could switch the power to the laser on/off to create your data waveform. You will have a limitation on your baud-rate depending on how fast the laser takes to turn on and off. To get past this, you could modulate only the power level to the laser. Then filter the DC out on the receiver side, while amplifying the signal to logic-level (0-5V).
But I've never done that, maybe someone more experienced should also post
