So I finally got this motor shield - http://buyincoins.com/details/new-v3-arduino-driver-motor-controller-shield-l298n-2a-2-motors-module-product-11952.html
which I'd like to connect to two motors, and send a PWM signal to change the speed. The issue is, however, I'm not entirely sure how to do it. It's all in broken english, which doesnt help :slight_smile:

If you take a look at the inputs (listed in order), I assume the following -
VEX - Voltage in?
5V - a 5v source to power the arduino
GROUND - ground, obviously
A- - Motor A ground
A+ - Motor A positive
B- - Motor B ground
b+ - Motor B Positive

I'm kind of lost as to where my signal is. There are 3 switches which the page mentions (VLO, VLC, VM), but again the english is pretty bad and I didn't quite grasp it all.

Does anyone have any suggestions on how to use this shield?
Thanks!

I agree the chinglish conversion is appalling.
Have a look at this link http://www.ebay.co.uk/itm/Motor-Drive-Shield-Module-L298N-V3-0-Arduino-Compatible-/280850808226?pt=BI_Robotics&hash=item4164033da2 or this http://www.ebay.co.uk/itm/NEW-V3-Arduino-Shield-L298N-Motor-controller-2-motors-/170814971161?pt=LH_DefaultDomain_0&hash=item27c55d9d19 as the explination seems better/more readable.

Thanks for the response! The links definitely helped.

For anyone that wants to know for the future, the code in the second link worked fine.
