    Hello everyone!
    My electronics knowledge is just basic. but i am a very cleaver and adaptive learner.

    My question is this. I need to have a Button that slides upwards to extend the connected piece upwards about 2 inches. here's my complication. I need it to cause an electronic sound ,but as it slides up the pitch changes. I cannot think if the proper components to cause this to work. Any help would be wonderful! Thank you.

    The solution closer to your need is probably a sliding potentiometer connected to an oscillator circuit.
