Doctor Strange’s magic circle
Doctor Strange can use the array as a shield, I think the picture is very representative.
The LED belt is controlled by Arduino around the shield, and the color change and sequence of lighting are controlled by a button (imagined).
Materials and parts you’re using
LED RGB light strip (have before)
Acrylic plate (bought 1/16 “12*18”)
Battery case (already)
Hand card slot (planned to 3D print)
Bearing (still looking)
The circuit may be so, the code is still uncertain
