Hello I have a 3VDC vibration motor that requires 95mA. I am a programmer, but I am new to working with the netduino and connecting electronic components using anything other than USB, RS232 or RJ-45. Any insight that could be provided I would greatly appreciate.

You'll want to use something like an NPN transistor or H bridge. You will also need a diode and a current limiting resistor to hook up in between the Netduino and the base of the transistor.

Use the Arduino relay schematic replacing the relay in the circuit with your motor. As Chris Seto mentioned, you need a diode and resistor, both of which are in the schematic. If you neglect to put them in the circuit, there is a very very good chance you will burn up the IO port on the Netduino board.

Thanks greatly for that, I certainly don't want to burn up my netduino on my first project that does more than blink an led in morse code

Using something like these should work shouldn't it?

I drive two NXT motors with this; http://www.sparkfun.com/products/9457 Works perfectly. Very easy to use as well.

This driver looks good. Would you mind providing some info on / pictures of your wiring?

I just used Solid core cut to length (8"), stripped 1/8" from one end, pushed it through and soldered. Was really easy. I'll get some pictures, but be warned, It's not industry-level soldering.

Thanks, I would greatly appreciate that. I'm sure your soldering couldn't be any worse than mine is.

I warned ya. Here ya go. I am only using one channel right now because It's just in testing. I'll solder up the other channel once I need it. The supply is a standard 9v battery.
