arduino motor shield

i am finding for a dc motor driver for arduino,
i found two, both i need to assemble myself:

  1. What Is Visual Programming and How Does It Work? | AppMaster

2)Adafruit Motor/Stepper/Servo Shield for Arduino kit [v1.2] : ID 81 : $19.50 : Adafruit Industries, Unique & fun DIY electronics and kits

which one is better, easier to use and has more support when i come to programming part?

is the both above motor driver bought the sensor bus up? so, i can connect my sensors.

any motor shield that already assemble and ready to use (plug and play)? i am from malaysia. any website suggestion for buying it?

anyone can reply me for the above questions? :-/
thank you. :wink:

These two products are different things.

  1. Is for driving DC motors, this is just turning them on and off and coping with the current. A DC motor turns when current is applied and keeps on turning until you stop the current.

  2. Is for servos and stepping motors and will also power DC motors. A servo does not go round and round. A servo needs a constant pulse train and then the electronics inside the servo convert the mark space ratio of the pulse train into a position that the motor output points in. The Arduino has software that produces such a pulse train on some outputs called PWM outputs.

A stepping motor can go round or point in a specific direction, it moves through a set angle (depending on the motor usually 1.8 to 7 degrees per step). To make it go round and round you have to keep supplying it with steps.

It depends on what you want to do with the motor what one to use.

personally, i think the adafruit shield is better and has more support - perhaps because i designed it :slight_smile: theres lots example code at Motor Shield - Arduino motor/stepper/servo control
the analog pins are brought up so connecting sensors should be pretty easy

I agree with you, your shield does seem like the best one, but every time I try to order one it seems to be back-ordered (including right now).

oracle, i agree with you, i faced the same problem that the motor driver is always out of stock.

luckily here i met ladyana, :slight_smile:

ladyana, how to order your board, i really need it as soon as possible.....
i am from malaysia (asia country), i hope to get it in one week time :-?

thank you for all the comments.... :wink: :smiley:

if you wanna go with steppers:
the easydriver from sparkfun.com works perfect with my robot, has a very small footprint (like the arduino nano) and needs two pins from the arduino

no, because the stepper motor is harder to program.... i am stupid.....

ok i get from ada fruit

you can always order if soemthing is out of stock and it will ship as soon as more kits are made

ladyada motor shield rocks! it´s easy to assemble and use :wink:

It is the best one there, I just wish there was something higher current lower voltage for cheap toy motors (and cheap enough that it's not wasted on cheap toy motors).

Can I really control 4 DC motors with ladyada motor shield?
Where to buy it in the UK?

Thanks!

I too would like to use motors with the arduino. I want to use a single stepper motor, and the electronics to do this is straightforward, but how much easier to buy a ready made shield. I've purchased from tinker.it in italy before but would really like to know if this is currently available from anyone in the uk. Im thinking of the ladyada shield but would look at others.

Alternatively, this design http://www.slscope.co.uk/electronics_projects/arduino/projects/dual_stepper_motor_controller/dual_stepper_motor_controller_2.html seems like the basis of a circuit that I could build possibly leaving out the circuitry for the 2nd motor.
