Good afternoon,

I'm just getting into Arduino (not an electronics buff) and I'm trying to build the motor speed control shown in this Instructible

http://www.instructables.com/id/Use-Arduino-with-TIP120-transistor-to-control-moto/

I'm finding it hard to get discrete components, and I have an old motor speed control kit (as yet unassembled) that contains these transistors

BC639, BC640, MOSFET STP60NE06/BUK456

Are any of these a substitute for the T1P120 listed in the Instructible  ?

thanks

LarryD

This is not a bipolar transistor like the TIP120 is, but it will work in place of it.
See the link below for some theory:

The way you have it in your schematic isn't the same as how you have it wired up!
