Arduino Motor Sheild?

Hello all Can I properly hook up an Arduino Motor Sheild to EZ-B, to run 2 DC motors. If so, can I get some sort of diagram/schematic? I need to be able to control the speed and direction if both motors individually. Sorry, noob question.

Additional info like what motors do you plan to use with the shield, operational voltage and amperage numbers that the motors require.

Just regular toy DC motors, not sure what the amps are

Without the dc voltage of the motors nor the power requirements to operate them I can't recommend that you use the Arduino Shield or even an H-bridge.

For a few bucks you can get the 2.5A H-Bridge which is most popular and has very detailed tutorials on usage with the EZ-B. Provided your motors don't draw more than 2.5A combined. You will need to know the current draw of the motors, without it you risk buying the wrong parts and possibly damaging them.

If you are dead set on using the shield you will need to find the schematic. Looking at the image you posted for it, there are connections that probably aren't required.

The connections are described here. Basically put, the EZ-B makes things easy so you just need to connect up the digital pins (3, 8, 9, 11, 12 & 13) to any of the EZ-B's D0-D19 ports, analogue (if you want current monitor) to the analogue ports, your Vin to Vin, Ground to ground and set it all up in ARC according to the digital ports used for the specific function.

Bear in mind that the shield is 2A per channel or 4A max. Make sure your motors don't need to draw more than that.

@Rich thanks dude, I think I got it. I'll play with it a bit.

After I saw this thread, my inner child kick in and was curious. I had an R/C car laying around along with Arduino and Arduino motor shield collecting dust. So I decided to give it a go. Yes it is possible, wire connection are very similar to the L298N H-bridge.
