Arduino controling electro pneumatics ETC help !

Hey

I am extremely new to all of this and came across Arduino only by research. Help and suggestions would be great!

I am wondering whether I can have an arduino board that activates electro pneumatic solenoids (that will let air through a component) and makes sure a certain pressure is reached in a certain time using a pressure transducer (one that relays back in anolouge signal) as the means of detecting it.
Then in the same cycle if you like, the same again would need to happen but a solenoid opening a vacuum line that tests the components ability to hold a vacuum.
After the cycle it would need to flash up with a pass or fail light for both the vacuum and pressure test.

Thankypu very much

So what i hear you say is.

You want to control some solenoids, and read a sensor that puts out a voltage, and control some lamps / LED's, and maybe a switch or two to continue the test.

If that is right then it should be possible.

BUT, you can not directly drive solenoids and other high current loads from Arduino pins, you need something in between, like a suitable transistor etc.

Also Arduinos ADC can only read voltages in the 0V - 5V range as is. This can also be changed with some extra circutry to either lower or raise the voltage.
