Simple LED circuit activity

Hardest part of this was teaching students to sew and thread needle. The conductive thread breaks all needle threaders we have tried. Adafruit website says can moisten thread, but do not place in mouth.

Hint – we now cut the thread after stitching one leg of LED light. Then, knot and sew next leg of LED light down. We had problems sometimes trying to use one thread for whole circuit.
