Halloween Circuit Costume

When kids learn about circuits, it opens a world of creative possibilities.  In Fall of 2020, after months of COVID restrictions and being stuck at home, my 6th grader decided that he wanted to be the scariest thing he could think of—a bad wifi signal! (seriously). So, we put our collective heads together and created a costume with simple circuits and sewable LEDs controlled by a micro:bit.  Below are some pictures of the process and a video of him in his costume.
