With Littlebits we were making a tickle machine.  How we made it is we had a battery.  Then we had a lead leading to the on and off switch.  We had a wire and finally a spinner that had a feather on it.  I tried it.  It really tickled.  Then I found a dimmer.  I put it on and when I turned it, the feather turned faster and when I turned it the other way it went slower.  I liked making the tickle machine.
