Alright I was wanting to know if I could use the potentiometer for my·"What's a Microcontroller?" kit with the piezoelectric speaker.· I am trying to create a vibration preception device with sound waves so being able to adjust the volume or control the amplitude of the sound wave would be nice.· Can anyone help?·

    Ok I guess I should have done better research before asking that question. I found what I was looking for...blush.gif·
    Ok new statement/question,· I want it to be louder,·how should I amplify the voltage from what is given from any pin to the speaker?· I will have my potentioneter in the circuit so I can control the volume.

    Again, a research question. Solution: search google for "amplify piezo speaker site:forums.parallax.com"

    Hmmm. Somewhat ironically, after some searching I was not able to find the thread about what is the best method to search... I wanted to link to it, but oh well. Yes, google is the way to go. Don't use the forum search function (button, top right) since it's quite terrible.
