I have a load activated by a button. I need it to gradually draw voltage and current as if it is being activated by a slider or knob. What simple, cheap device will do that for me up to 12v 3.5amps? [ex.png]

How do you make the current draw from a device gradual instead of instant?

Can the load be PWM'd ? What is the load?
