Hi so I am having trouble thinking this up as I don't have any kind of software to draw what I want and I totally suck at mechanics.
Anyway I am after building something which will open and close a plug on a water tank by lifting it up and shutting it when I want to, controlled by a motor controller and a PIC all isolated and I will think about waterproofing later.
But yeah, I am thinking to attach a servo to a rod which will then be attached to the bottom of the plug this will obviously have to be outside the flushing pipe of the plug, I am really not sure how to get it to lift up and down.
Any help would be grand.
