Lights connected to VMA400's and Arduino Uno

Dear,
As a lay-person, looking for a (simple ?) C# program to fire and estinguish in sequence N lights (i=1-N) during Ti seconds.
To be used in an art school exhibition on this year’s ‘light’ theme, in a dark room where N artworks are to be connected one at a time in a looped sequence in order not to ‘light-pollute’ each other.
Grateful thanks for your kind help.

Dear,

Maybe the sample code at page 4 in the manual can help you further.
