Hello, I am completely newbie in arduino stuff..
I have 3 Chinese 6000l/h aquarium wavemakers I would like to use if possible as wavemakers with controller operate...
The wavemakers oprate in 220v
I used the following pwm voltage controller to controll the speed of the wavemaker and it works just fine...

I used it seeing the following video
Obviously it is not possible to turn the potentiometer knob low high every 2 seconds manually to make waves in my aquarium...
So the question is, if it is possible using arduino to controll what the knob does... maximum for 1 second, 30% for one second, in loop...
Thanks for your time and sorry for my bad English!!
