My question is about hardware that i'll control with my arduino... Not Arduino itself (So I don't know if I'm in the right section ... :s)
My project is to create a cocktail machine at the cheapest price.
My idea from now is to use only 1 water pump (as this one) and connect all the pipes from the bottles with some Y and control which one is giving the liquid by controling pistons that are going to compress the tube.
I'm open to all advices you could give me and new ideas ... I saw that there's also solenoid valves ... But I only find it in 12V ... Does it exist in 5V ?
