I'm looking for a mechanical component that enables me to do two things:
- contain a gas in a bottle and if opened, the gas should smoothly flow out (with the same pressure as a child blowing out candles on his birthday cake)
- a valve for the bottle that can be opened by an Arduino when powered via USB
I already figured out that there are outlets for CO2 capsules. This could work, but then I'd need to figure out a way to decrease the pressure in order to receive a gentle gas flow.
Do you know any better approaches? Thanks in advance!
