I am making a complex project that needs to use transistors to "trigger" certain events that is greater than an adruino's voltage.
An example of this is I need to use 30V or higher to use on the project than 5 or 9V than the arduino uses.
The main problem is can one pin connect at least 2 or more GATES in a transistor? (the middle prong in the transistors) AND does it have to hit ground on the pins once complete, or is there a different way?
If not is there a way to insert multiple programming by switch? The switch is an input I think.
can you show the diagram exactly? its hard for me to read words sometimes without pictures. So after one gate add a resistor then so on? all connected in series? or parallel?

It would be quicker for you to Google it, than come back to me if you are unclear.
Bainesbunch:
you can drive multiple MOSFET gates from a single Arduino output, be sure to use a resistor for EACH gate however.

NPN's would be trickier because to fully saturate you need around 200ohms but that also taxes you on current, so try not to go over 30ma total draw....
NitroXAce:
I kind of meant NPN and PNP, but I will take the FET's on consideration, but what setup does it need extra to work?
It's relative to the collector current required.

That's relative to the collector current required, too.
So, there's not a one-size-fits-all solution that I can just plop before you.
I could say, "well, just overdrive the crap out said transistor", but that'd be kind of clumsy like.
MOSFETs don't have the input current : output current relationship that bipolar transistors do.
You'll have to be more forthcoming about what you're trying to switch on the 30V.

I'm not poking fun or trying to be a hard-adze, but What are we talking about here?
