Right i am new to Arduino's, but i do have a basic understanding of programming. I am doing a little winter project, trying to design and program a pneumatic shift mechanism. I have four 2 way pneumatic vales that i would like to control and program a series of events.I have no idea what Arduino equipment or programs i will need to do this, firstly to switch the valve from position 1 to 2 the 12v polarity will need to be reversed. There will be 5 events, i would like to cycle through them with two buttons, one button to cycle up the events and another to cycle down them. Each event will always include at least 2 relay triggers. i would also like each event to take less than 500ms.As i said i am new to this but would really like to get to know Arduino's and take full advantage of them.
