ADXL335 changing capacitor to change bandwidth has no effect. I can measure >50Hz even while this shouldn't be possible. Why?
The Adafruit ADXL335 analog accelerometer comes per default with 0,1 uF caps, thus setting the bandwidth to 50Hz. See Datasheet: https://www.analog.com/media/en/technical-documentation/data-sheets/...
