What is the Code Doing?

The code loops forever, first moving the servo motor from 0 degrees to 50 degrees (with a .9 millisecond pause between angle changes). Then the code waits 150 milliseconds and reverses the angle of the servo from 50 degrees back to 0 degrees. The movement is timed to be fairly fluid without being too fast or too slow.

If you find the movement too fast or slow, adjust the times of the pause statements directly below the servo write block. A small addition or subtraction will do, you do not want the wave to be super fast or so slow.

The switch on the battery pack is used to turn the project on and off.
