OK.
Some more questions that popped out: Do I connect the pressure switch to a spike too?
And if not, then how do I connect it directly to the digital I/O port?
I could also use some sketches according how to connect everything (where does the pressure switch go, where and how do I put the air tanks (the accumulators), how do I use the solenoid valve? Where do I connect the solenoid valve (to a spike?)).
As you can see I have no idea in pneumatics, so I'll need some basic information about everything.
