The assignment is to come up with a simple application for switches and LED circuits.
In the first place, I was thinking about making a switch that can turn on and off automatically. But I could not give up the idea of using the water. So I tried to combined both of them. Then the idea of teeterboard come to my mind. Because teeterboard is a very interesting balanced “machine”. It is very like natural thing that everything has an opposite section and to some extent it could be balanced to a central line.
Then I have the idea of controlling the connection between two part of water with teeterboard. When they are connected the circuits will be close and the led will turn on.
So I started with grabbing things from the junk shelf and I got two great handle to serve as my support feet of teeterboard. I cut some dumped wood board as part of it.
And here is what I got.
