Moving engine slider control

This animation is the first one that we have written using slider control on the screen. To start the animation press Start. After this the speed of the engine, backwards and forwards, can be controlled by moving the slider to the left or the right.

The motion may be stopped at any time by pressing Pause and Reset by presssing the Reset button. You will then need to press Start to begin the animation again.
