Hi guys. I have been out of the xmas lighting for a few years as we bought a new business a couple years ago that has taken ALL of our time. Finally I can see light at the end of the tunnel as we have managed to almost finish moving premises and getting some employees to take the pressure off.
Sooo......
We have a fence frontage that is approx. 20m long and is about 600mm above ground level with a flat grassed front verge. We often have kids (and parents) dancing on the verge to the music and I wanted to have some kind of movement control of the fence line where as someone moves up and down the fence line the lights will "follow" them.
I was thinking ir sensors, but they, I would assume, would be too hard to narrow a beam and would just go off almost randomly, Then I thought some kind of infrared beam, but a reflector would make that impossible.
I am not 100% sure on ultrasonic but think I may do some testing with them and an Arduino
Has anybody had any experience using these that they can offer or indeed has anyone done anything like this that they offer their advice?
