I was wanting to created a fountain that has three separate pumps. Each pump would turn off and on for several seconds at a time, or even be randomized. I have been told that I might be able to create something using a Raspberry Pi. Unfortunately, I am completely unfamiliar with this product. Does anyone have suggestions. There is an aftermarket product that has three pumps and 12 different settings but it is over $750. All help would be greatly appreciated.
