I am using this circuit for a model lift up and down functionality. Vin is +12V. The output voltage is controlled by the 10K linear potentiometer that varies the final output from 3V to 12V. The DPDT controls the direction of the lift by reversing the polarity of the output voltage. The only problem is, when the pot is adjusted, the voltage drops or increases instantly giving the lift a jerk. Is there a way to smoothen the process so that the Voltage drop or increament is delayed over a few seconds? I have tried to increase the value of the output capacitor to 1000uf but it did not help.
I guess moving the potentiometer more slowly is too obvious?
Place a resistor between the wiper of the potentiometer and the 10 uF capacitor. 100k will give a 1 second time constant. For a still higher time constant I'd increase the capacitor rather than increasing the resistor.
