I think this would be a great topic to talk about, as the optocoupler 4n35 does come with the Arduino starter kit. Some real-world examples on using it would great/compared to a releay
@acode I was going to point you to the video regarding opto-couplers at this site, and could not find one. I agree they should be covered, but from a more generic method of how to read the datasheet to bias just about any opto-coupler.
It's hard to imagine devoting an entire video/article to the 4N35, it's a pretty standard component that's been around for decades.
I briefly mentioned optocouplers in the Controlling AC Devices with Arduino article, but not the 4N35 specifically.
Does anyone have any ideas about how to put an interesting spin on this? I do have a drawer full of these already!

I used them to isolate the 5v circuit controlling a 12v H-BRIDGE circuit for a robot base.
