Quick question for a future project.
How could I make an Arduino spray a liquid? As in, shoot out the liquid? Perhaps with a normal spray can somehow hooked up to an Arduino? So yeah, basically an electronic spray can.
I could make the Arduino spray water at people!! OR I COULD MAKE IT SPRAY A FLAMMABLE LIQUID OVER AN OPEN FLAME, MAKING IT SHOOT FIRE!!!! (Not saying I'm gonna do that)
Thanks in advance!
