I'm thinking of using an arduino to control a jetmotor of a whirpool. the motor is now activated by an air pressure switch but there is always coming moist in the airhose and then i have to clean it again.
My first thought i to use a touch sensor to switch the motor on and off and control the speed , for example full or half speed. The thing is, that the touch sensor could become wet because off the place where it's going to be. Could that be a problem ? The second thing is, i want to be sure that there never comes 230v on the touch sensor, how can i accomplish that ?
I really appreciate any help you can provide.
