For this week’s assignment, at first I was trying to sew the SMA as a thread to see how it works. But soon it got tangled and started breaking. After that I took the SMA out and sewed it on to a kind of fabric which will have a nice wrap while being pulled. In the beginning I used to much thread to sew the SMA onto the fabric that when it is heated it didn’t have enough space to move. Then I cut out some thread, it started working. I used a pressure sensor which is connected to the analog input on Arduino and mapped the analog output according to that.
