Hi I need a H-bridge circuit to control a 9v DC motor with Arduino using 2n2222 transistors. Thanks. 8)

Was there a question to follow that or are you simply stating that you need an h-bridge? If so I would recommend something like l298n motor driver. If you do have a question about an h-bridge circuit than please do ask it.

Google would be a good start. You might get an H-bridge on ebay for $5 shipped if the motor is small.

I was looking to build one out of transistors. Sorry if I was not clear. 8)

Well, save those links as typical DIY h-bridges don't work or cost more in parts and time. Google "h-bridge schematic" for lots of diagrams.

Actually, for his question, googling "BEAM h-bridge" would be a better alternative; though you're not going to get there with just 2n2222 NPN transistors (you'll need the PNP complement, 2n2907 or similar). Far better, though, would be to use a L293...
I will not respond to Arduino help PM's from random forum users; if you have such a question, start a new topic thread.
