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.
