That’s interesting. I need to grab arduino and test it out, I would like to generate sound input into microphone with a laser diode. I don’t care that I won’t be able to generate words, but think of it - sending sound to my phone microphone via laser? That’s just cool. Thanks for the link, I have something to do at the weekend.
For those interested, arduino analog output pins send PWM in 980 Hz (might be possible to go higher), which is inside human hearing range. I have no idea how wíl laser light frequency map to sound wave frequency, but I’ll sure try it out.

And yet, it does.
