Trafic Lights

January 17, 2013



They built and programmed traffic lights.

They built a gate that has touch sensors to know when it is completely closed and completely up.

It also has a light sensor to "see" if money has been paid.


The program waits for the money them opens the gate for 3 minutes and closes.

They figured out how to put this all together.
