Press the setup button, then go . Press go again to stop. Press setup again to reset.

Let the sim run for 1500 clock ticks or more. Notice how the driver starts to oppose the resonant waves, and starts to deplete their energy. After the resonant waves are reduced to almost zero, they start to build up again, and a very long cycle is repeated.

Set the driver frequency to about 46.4 . Reset and let the sim run for a long time. What happens? Reset, and reduce the driver amplitude to less than 1.0 . This shows how resonance lets a small energy input build up into a large amount of stored energy.
