After class, I undertook some further testing to find a solution for flipping our dots back and forth without having to constantly reverse alligator clips. I found one solution on this post from Stitching Worlds.
Instead of using one coil, create TWO coils and embed them in your crochet or embroidery ring (be sure to mark which coil is which). Each side gets its own power source. When you switch between activating a coil, it will flip the dot back and forth (one side is regular hemetite and the other has a bit of copper paint on it):

The door is supposed to open and close on it’s own. I thought it was ironic to have a Do Not Enter sign on it. I tested out with Arduino first, but it wasn’t working for me. Then I tried with the 9v battery, but I didn’t have a 12-13 resistor. I tried using a 220ohm, but it still wasn’t working and I was afraid of burning it. -Estee
-Estee, I used foam board and copper tape for the base. Then I cut foam cups into the shape for better echo of the sound.
The first connector was the probe connector we’ve learned in class, we took off the inside of rope out and put in three conductive threads, then we make a knot around a pin and close it off using polymorph.
For my second connector(the bottom one of the image above), I paste copper tape onto a plastic stripe that is made out of a plastic sheet and on each side I put a paper clip into it. Then I solder the copper tape and the paper clip together.
For my third connector(the top one of the image above), I used the same method with the putting the conductive thread in but this time pulling the rope tighter so it makes a wave. On each side of the rope, I used a keychain ring and closed it using duck tape.
For my fourth connector(the bottom one of the image above), I did the same method as the rope we did in class but this time I used safety pins on the ends. I closed on safety pin with duck tape and another one using heat shrink tube.
It’s really great to find new fun ways to connect the circuit together.
