I am creating a project that will replicated a car sensor that is not made anymore. The sensor is mechanical and detects vacuum pressure and an inductance coil is adjusted that changes the frequency of the input signal. You can see an image here:
Now I have a vacuum sensor breakout board that gives digital readings based on vacuum. Now I need an inductance coil that can be changed via the arduino based on those readings. All coils I have found are in the style of a pot that can be adusted with a screw driver. I am looking for something that can be adjusted via code. Any ideas on how to go about that? Thank you!
