This is my first time using Arduino, although I have some microcontroller exposure with the Basic HomeWork board. I am interested in powering multiple (6-8) very miniature solenoid valves to fill small, tubular balloons. I want timing to be flexible, although generally the filling/emptying of each balloon will follow a wave-like function. I may choose to connect the solenoid valves to a manifold or similar device, along with a pressurized air source. I have not selected a particular solenoid valve, although I am considering 3-way valves, as I can allow the balloons to deflate as they would regularly. I was wondering which Arduino product would be optimal, and whether the I/O pins can deliver enough voltage to solenoid valves of a miniature size. If not, would I have to design a driver circuit for each solenoid valve?
Thank you for the help in advance!
