I am at the point where I have to turn on the professors projector. However, I can not figure what I am supposed to do. Can anyone help?

The white ovals have 3 rings.
You have to change the color of the rings so that when the rings are combined they match the colored ovals-fuses at the bottom and right columns.

I just took a picture of the solution.
Tell me if you want to see it after trying.

Thanks, I got it now.

Great. Have fun!

Wait until the 3 mazes. Ugh!
