Guys, I could use some help on a fun project.
Electronics is not my thing.... so go slow with me?
I've come into possession of a "semaphore", hanging stoplight. Red, yellow, green. Old school. Very.... um.... kool. Haha
I'd like to wire it up in my garage, such that it acts to alert my wife how far into the garage she is. So, green when she enters the garage, yellow when she's in far enough, and red when she needs to GO NO FURTHER! Haha
So, I can imagine a photo electric beam switches and relays setup, but it's not clean, and I'm not sure how to switch off one color when the next comes on, and then how to time them out after she parks.
I imagine there are really easy ways to do this, for someone who knows how. I'm appealing to y'all.... 'cuz there's some smart cookies here!
I'd love to learn how to do this, but if the curve is steep, I'd also be very happy to pay someone to build it for me. (I'm not getting any younger here! Haha)
Waddy'all know?
