Project Help and Ideas » Nerd kit as an oscillator?

Is it possible to use the nerd kit as an oscillator? For a project I'm working on, I'm measuring the frequency response of fluids in a capacitor and was wondering if there was a simple way to use the MCU as an oscillator to generate a 100kHz AC.

Thanks for the help.

No, a microcontroller is a digital device, that means you can generate only a square wave of 100kHz. If you are looking at a cheap way of making a sine wave, use an op-amp, refer to this document to find how to make one.

And this page has a lot of different applications for op-amps including a sine wave, square wave, and triangular wave generation.

Did you know that sound travels via pressure waves in the air, and you can make these with a piezoelectric buzzer? Learn more...
