Piezo Output

[doctorcpu]

Hi,

My son's favorite games uses a Piezo buzzer for sound, How can I use a transistor to turn an LED instead. Just want to remove the buzzer and replace it with a LED. When I measure accros the buzzer I get 1.5 volts DC, but this varies when the buzzer starts.

Any help is appreciated

by the sounds of it you shouldnt need a transistor.
just solder/crimp/attach the led where the piezo was. check polarity.
