Timer to alternately show/hide 2 objects

Question

Hi,
I'm trying to learn how to use a Timer and AS3 to set up 2 objects (for example, 2 squares, each with a separate instance name) that would show/hide alternately for 500 ms each for 30 seconds (30000 ms) total. Easy enough to do using a timeline, but instead, I need to set this up to include using AS3 to add to a companion .as script file (Main.as), which loads and all runs on Frame 1. I first looked at using setTimeout or setInterval, but these don't seem to have enough properties to do what is needed. So, Timer is probably the best choice. I've read the online documents and examples for a Timer, but still can't figure out how for example to alternate one object's 500 ms show with the other's 500 ms hide, then alternate/switch them, and stop the alternating sequence after 30 seconds.
Any help, example AS3 script would be great help.
Regards,

Hi Ned,
Unfortunately that's what I have been trying, without success. Actually, have gotten fairly stuck in experimenting and am hoping that someone can provide a simple example. The following is some of the "gibberish" that I tried without success.
private var c1On: uint = 500
private var c1Off: uint = 500
private var c2On:uint = 500
private var c2Off:uint = 500
private var c1OnTimer:Timer
private var c2OnTimer:Timer
c1OnTimer = new Timer(c1On, 30);
c1OnTimer.addEventListener(TimerEvent.TIMER, c1OnF);
public function c1OnF(event:TimerEvent) {
mcsquare1.visible = true
mcsquare2.visible = false
c2OnTimer = new Timer(c2On, 30);
c2OnTimer.addEventListener(TimerEvent.TIMER, c2OnF);
public function c2OnF(event:TimerEvent) {
mcsquare2.visible = true
mcsquare1.visible = false
c1onTimer = new Timer(c1On, 30);
c1onTimer.addEventListener(TimerEvent.TIMER, c1onF);  
//onTimer.start();
}//end
public function c1onF(event:TimerEvent) {
mcsquare1.visible = true
mcsquare2.visible = false
}//end c1onF
c1offTimer = new Timer(c1Off, 30);
c1offTimer.addEventListener(TimerEvent.TIMER, c1offF);  
//onTimer.start();
}//end
public function c1offF(event:TimerEvent) {
mcsquare1.visible = false
mcsquare2.visible = true
}//end c1onF
