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.

Since it's a DC, a general purpose logic level MOSFET is enough. Something like this will do the job just fine. https://www.sparkfun.com/products/10213
