PBL Lights Project Basic Questions

1) What are you going to build?

My team and I have decided to make an automatic light switch so the lights will turn on without anyone having to press a switch. It will come in handy for saving electricity, as it will turn off when someone leaves the room. Basically, if anyone enters or leaves a room, the lights will turn on.

2) Why have you decided to build this object (energy transfer system) a working model?

We heavily debated about what we were going to make a model of. We had many ideas, and we researched for a few lazy-people problems. At first, we tried to think of any way possible to turn on/off the lights without having to get up. We thought of any ideas, I even suggested a really long stick. We finally agreed on a motion sensor and we decided that it was about more than just a lazy-person problem. We could save energy for people.

3) What materials are you going to need to complete your build?

We will need:

-A motion sensor.

-Some wire (maybe around 12 inches).

-A few large-ish lightbulbs to test it.

-A door (we could use a cardboard one).
