I'm designing a scene for an upcoming DnD session that includes a puzzle involving a central monolith stone covered in runes and several smaller stones, each with a single rune. I want to make it more exciting by incorporating lighting effects—specifically, when my players move the smaller stones to the correct location, the runes on both the smaller stones and the monolith should light up. I've dabbled in basic electronics and thought about using Reed switches, but I'm not sure if that's the best approach. I also considered using induction coil zones, but that would mean all stones light up when within range, which isn't what I want. I'm not great at coding logic for this sort of project, so I'm seeking advice!

Reed switches are a great choice! If you set them up in series, they will only light up when all the corresponding stones are in the right position. This way, whenever the players get it right, they’ll immediately see the runes light up, which adds to the excitement!
Totally agree about Reed switches being simpler! They align well with the KISS principle—keep it super simple! You won’t have to deal with any coding or debugging issues, so it sounds perfect for your puzzle setup!
I’m a huge fan of the KISS principle too; it really helps in projects like this!

That could work! It’s a straightforward way for them to see they did it right, and then they can roll STR checks to move the stones around!
