For this week’s homework, I experimented with SMA to create an unhappy cat taking a shower.

I began by drawing the cutouts of the shower and the cat and made a box to facilitate the up and down movement. For the handmade sensor I made a rotating sensor with some paper, copper tape and screw nails. The sensor did not work out as well in the code, so I ended up not using it to activate the wire.

Then I started experimenting with making the wire move. I had a lot of difficulties controlling with Arduino because my battery wasn’t working well. I tried using analogWrite up to 50000 in value to make it move.

After switching batteries it was operating better.
