Hi all,
I've faced an issue, when I using only one DC motor, everything works like a charm,
but if I connect two motors simultaneously, one motor works OK, but another in few times slower.
(currently I'm using Arduino 2560 MEGA board)
Any help is appreciated,
thanks.

Re: Motor Shield Issue with DC Motors
What motors are you using and how are you powering them? Is the slower motor always on the same port?

Re: Motor Shield Issue with DC Motors
Hello,
I use DC Motor260 two pcs., one of them I connect to the M1 port, and another to M2.
I supply motors with two separate sources - from Arduino, and extra - with 9V from battery.
I've tried to connect motors to different ports - seems to be the same result.

Re: Motor Shield Issue with DC Motors
Do you have a link to a product spec for that?I use DC Motor260 two pcs
Not a good idea. You should use one or the other.I supply motors with two separate sources - from Arduino, and extra
Is that a 9v battery pack, or one of those little rectangular 9v batteries? The small rectangular ones are all but worthless for driving motors.- with 9V from battery.
If you swap motors and/or swap ports, is it always the same motor that is running slow? What if that is the only motor connected?I've tried to connect motors to different ports - seems to be the same result.

Re: Motor Shield Issue with DC Motors
thanks for reply,
I'll check and update you with results.
Also I have a question, what is the best solution for supplying motors?
(only from extra source? if yes, what kind of power cell I have to use?)
thanks
