best solution to turn in sequence a series of spotlights

Hi all!! I hope this is a correct section for my topic!

I would know what is the best solution to light up in sequence a series of spotlights. I wish that when I give the command switch, the spotlights on my stairs light up one after the other in sequence.

I have to use arduino and relay? or is there another way smarter

thanks regards. S.

Depends on the spotlights you want to use.

hi Shpaget, thank for your response. like this

Since it's a DC, a general purpose logic level MOSFET is enough. Something like this will do the job just fine.

thanks a lot shpaget

Hi, use the Search Arduino Forum tag at he top of page and search for stair lights There have been a couple of projects similar to yours here before. Tom.... :)
