Arduino Motor Shield & Canakit Stepper Motor

for a start you`ll need a driver board or chip, a simple Dual H-Bridge chip will do the job, do you have such a driver?

after that the rest is quite trivial

I have an arduino uno as well and a

EasyDriver Stepper Motor Driver

can you guide me to the next step with the wiring

here is the Chip used on the board http://www.allegromicro.com/~/Media/Files/Datasheets/A3967-Datasheet.ashx so you may be able to work out which wire does what function and goes where..

is there any reason it`s not actually marked on the boards silkscreen what each wire does?

Are you saying there is no easy way to just connect the canakit stepper motor to the arduino uno and or the motor shield to drive this moto

well, it`s not Plug`n`Play like some of the shields that have the SIL headers on, that simply fit onto the arduino itself, but it`s almost as easy if you can solder.

you`ll need your 4 stepper wires to go onto the board, these are usually organised by color.

you`ll need 2 Grounds, one for the Arduino, and one for the motors power supply, these will often be commoned.

you`ll need your 5v power from the arduino board, and a seperate power source for the motor, Dont try and run the motor from the arduinos Power supply you`ll blow the regulator!

then you`ll need to elect some arduino pins  for the motors control logic, these can be anything from basic Clock and Direction pins, or direct switching whereby you present the step code yourself, a typical 4 bit bipolar number sequence would be; 9, 5, 6, 10. and then of course the reverse of that sequence to turn the other direction.

You may have an option for limit switches, you can ignore that for now though.

ok, I`v just had a quick look at the data sheet, and it seems to be a simple Clock and Direction type of driver, these are really nice (and simple) to work with!

a basic algorythm to test it would something like this:

Direction pin 12 = out

Direction pin 13 = out

delay = 10

Start:

pin 12 = 0

gosub step

pin 12 = 1

gosub step

goto start:

step:

for clock = 0 to 200

pin 13=1

wait delay/2 ms

pin 13=0

wait delay/2 ms

next

return

this will turn you motor around in one direction for 200 steps, and then reverse the direction and turn the other way for 200 steps.

this will be done at a 100Hz rate.

also you`ll have to turn this into arduino code as it`s just a raw basic code at the moment, but it will work

there is also an Enable pin (active low) on the chip diagram, I`m not sure if this is brought on the board you`re using at all, but if it is, you need to connect it to GND.

hope this helps!
