So I guess this is a basic electronics quesiont.
I have a breadboard, and put these parts together from these directions:

If I wire the blinking LED up in parallel with the piezo, the piezo doesn't beep. It only makes a solid, but louder, tone.
If I wire the blinking LED up in series with the piezo, it beeps, but both the light is dimmer and the piezo isn't as loud. I suspect this is because the blinking LED doesn't open entirely up when it's not lit.
I tried the LED backwards, and it smoked. It no longer blinks, now it's just a solid LED
Any ideas?
Perhaps I got the wrong part.
