Research for my interface

So today we final get our starting kit for the arduino, hopefully all my plan was basically like the timeline plan. 

Have a deep research for the LED walk path light

Here! is the basic tutorial show me about the principle for the PIR motion sensor.

Today's tutorial work.

There is also one of good example to show proximity sensor for the project. Might be give me some idea about distance between the user and interface. I could tried to use that kind of idea to put on the my  project. The link about the proximity.
