O Christmas Tree

December 9, 2010

They listen to the version of O Christmas Tree that ways made yesterday.

They they programmed the music and lights to go together by making the times for the lights very short
and figuring out the number of times the loops need to go to end the same.

Then they programmed the lights and music to go on when the touch sensor was pushed.

They got the robot to push the button.
