In this assignment, I made a mini character that comes alive when its little hands are touched. The mouth appears by thermochromic pigments, and the eye lids roll up.
I found flexinol really troubling to work with and it took me numerous iterations before I got them to roll up properly. I realized the real trick is to be able to stitch the flexinol on properly. Finally, I realized the power is much greater when using the battery directly, by-passing the circuit and the arduino altogether.
