Tell us about yourself!
I suggest using Mosfets and either a Arduino with enough pins (stairs+2) or some other control mechanism like shiftregisters.If each ledstrip is connected to its own pin its easy enough to write the code.
Hello I find this a nice project but I rewrote the code (had some spare time) hope you like it https://we.tl/KOozjotBdhits not perfect but should work if not or you want explanation don't be afraid to contact me ;)
This would make it so much more complicated but a third option could have been capacitive sensors since you wouldn't have any lazers shining
I have looked at the code and it should light up for more people but in a not so clean way but I have reworked the code and now it should support that
also here are some other pictures
well no it really does show the next block This is simply done by generating the next block when you start placing the current block And I use MIT App inventor http://ai2.appinventor.mit.eduto make the appit has its limits but is easy to use
I made one a while ago https://www.youtube.com/watch?v=aBFZeL3S1zs
LEDs and Lighting Class

I tried but I get this (see pictures) please help me
