arduino simple + light sensor

Other Hardware Sensors
1

Hey!
So I just started my adventure with Arduino and I am already having a problem. I am trying to hook up lilypad simple with light sensor and I tried so many codes (which changing the pin number correctly) that I started to give up.
I connected '-' on light sensor to '-' on the board, '+' on the sensor with '+' on the board and S with 9 or 5. nothing worked.
help will be really appreciated.
thank you

This is the Lilipad Simple : http://arduino.cc/en/Main/ArduinoBoardLilyPadSimple

The Arduino Uno is the easiest board to start with.
To get to know Lilipad Simple, perhaps you should first try a few other things.

Can you make the led at pin 13 blink ? Can you make it blink faster and slower ?

Next step is the Serial library. Did you try sending messages to the serial monitor ?
That is essential to test sensors.

Which light sensor do you use ? You can copy a link in your post.

Ok seems I figured it all out.
My current question though is how do I introduce in a code more than one sensor and then indicate that each has a different function.
Let's say Im using temperature sensor and I want to to print in in a serial monitor whether its 'cold' or 'hot' depending on my settings. And then there's also light sensor and I want it to do the same except it's gonna print 'white' or 'black'.
Thanks

Well you would have two variables, say "myTemp" and "myLight". Then you choose two threshold values say 25 for cold/hot and 500 (out of 1023) for white/black. Then you just say:

if (myTemp > 25)
{
Serial.println("hot");
}
else
{
Serial.println("cold");
}

...... and similar for myLight.
