Example Explained

The example gives an impression of a battery getting charged, but instead it is five different icons being displayed.

A function called chargebattery() does all the replacing and displaying of icons.

The function starts by displaying an empty battery icon:

After one second, the icon is replaced by a new icon:

The icon is replaced by a new icon each second, until "the battery is fully charged":

This process is repeated every 5 second, making it seems like the battery is charging.
