Animator[u,{u_min,u_max}]

makes u vary from u_min to u_max.

Animator[u,{u_min,u_max,du}]

makes u vary in steps du.

Animator[u,{u_min,u_max},ups]

makes the value of u increase at a rate of ups units per second.

Details and Options

The default duration is five seconds.
Animator[Dynamic[s],…] makes the value of s be continually reset with time.
Animator[u,{u_min,Infinity}] will run forever, with u increasing by 1 every second.
Animator[u,{-Infinity,Infinity}] also allows u to decrease forever if the animation is run in reverse.
The following options can be given:

AnimationDirection	Forward	the direction of the animation
AnimationRate	Automatic	the rate at which to take variables to vary
AnimationRepetitions	Infinity	how many times to run before stopping
AnimationRunning	True	whether the animation is running
AnimationRunTime	0	time elapsed since the animation last started running, or 0 if the animation is not running
AnimationTimeIndex	Automatic	time index for the animation, where 0 is the beginning and the value of DefaultDuration is the end
Appearance	Automatic	the overall appearance of the animator
AppearanceElements	Automatic	elements to include in the displayed animator
BaselinePosition	Automatic	what to align with a surrounding text baseline
BaseStyle	{}	base style specifications for the animator
DefaultDuration	5.	the default duration in seconds

Enabled	Automatic	whether the animator is enabled, or grayed out
Exclusions	{}	specific u values to exclude
ImageMargins	0	margins around the image of the displayed animator
ImageSize	Automatic	the overall image size of the displayed animator

The following elements are included in a default animator: "ProgressSlider", "PlayPauseButton", "FasterSlowerButtons", "DirectionButton". These elements can be specified in any order in a list given as the setting for AppearanceElements.
