Variable frequency generator? Answered

I'm looking for a way to build a simple frequency generator that generates high and low frequencies. I was thinking of using a POT to control the frequency range. I looked for it all around but the search didn't help much.


Have you done a search of Frequency Generator schematic on Google. Found all sorts of schematics on the image search. Check out the web sites that posted them and see what ranges each one offers and modify things as needed.

Using your method, i found that a variable capacitor is a better option. Just need to find some.

Decide on your circuit first. Finding the variable capacitor won't be hard they are still available.

I wouldn't bet on it being a better solution
