DIY H-Bridge Shield for Arduino With Transistors

Components needed to make the shield-

8* NPN transistors (I used some BC 547 and some 2N2222a because I didn't have 8 of either one) 8* 1k ohm resistors (a value close to that should work) Stack Headers (optional) Pin Headers 9V Battery and clip Perf Board

Hey, if you want a fun project for determining if your transistor is NPN or PNP please refer to my 'The Transistor Testenator' instructable.

You, of course, need to have an Arduino and motors. A breadboard would also help as it allows you to prototype the circuit before soldering it permanently on to the perf board.
