Ok, I know this'll sound dumb, but I need some help here...
I have 2 solonoids which control a flow of air which is around 100 psi...I need to switch these back and forth via a lever switch...once the lever switch is activated, it needs to activate solonoid 1 instantly, leave it open for .9 seconds, then activate solonoid 2 .2 seconds after, then leave it open for .3 seconds...mainly I just want 4 variables that I could be able to program that would activate these solonoids in the right timing matter.

How can I make it so I can program a chip, etc to do this?...I have to be able to switch it into my computer then switch back, or even keep a constant connection with the chip while its also connected to the solonoids...

I plan on making some electronic boards for a paintball marker, which would include turbo, burst fire, etc...

Also, where is a good place to learn about what circutry does what?...

I know a reed relay will close a circut when a current is passed through it...that's been useful for making blinking LED by tapping into the solonoid power and using that to blink a light whenever the solonoid goes on...but I need to know what certian resistors, etc do...like a voltage regulator...I've seen 'em, but do they overheat, etc when too much is put through them?...what if I wanted to only put out 5 volts, and 12 volts were input?
