    Hi, I was wondering about adding in wind control to my yet to be built setup.
    Is it best to add a second arduino and an IBT2, or can one arduino stand to add in a fourth control with 4x IBT2`s without losing control resolution (gets jerky)?
    I have searched on here can`t really nail it down.
    @noorbeast, I`ve looked at the first page of your build, it seems awesome. Did the 40kg pair of servos help a lot, or would I be better to add the fourth IBT and a larger motor for it instead of a pair of servo`s?
    Currently I`m at the design and gather stage. I have four IBT2`s two decent wheelchair motors, one wiper motor, one shop sliding door motor with associated belts and pulleys, another pair of large geared motors off of an industrial screen printing enlarger.
    I accidently ordered 3x 60 degree hall effect rotarys, didn`t notice until they arrived. Ahh well I`ll make them work

    Hi Notcloud, you will need a separate Arduino/Motor driver for wind. The wind arduino would use a different sketch from the one running your motion.

    But can I stream the two sketches into one sketch, or is the Arduino not powerful enough? Whilst I'm not the best coder in in the world, I am a coder nonetheless

    I suggest 2 arduinos

    3 motors on one board

    A wind sketch on the 2nd board

    You will need to create a custom program if you want a single arduino to do both jobs

    Simhub can program an arduino/nano automatically to drive a wind fan

    Can an single Arduino drive a 6dof? If so the I bet ad
    Bother. Wasn't wearing glasses and on phone. I may have closed the thread. Help admins!!

    Ultimately I redesigned my rig and did away with the servos, I would suggest a bigger motor for dedicated axis, more powerful at similar cost.

    I found this guy to be really helpful when setting up a wind simulation.

    Thanks

    Thanks for the link and the input guys. For simplicity two arduinos looks better. As the nano is according to what I read, identical to the Uno in connections but in a dil30 format, I may go down that route as they would at least take up less room, and are easier to implement into a custom PCB. Talking of which I've just ordered a small usb CNC router which should be able to create PCB's. Plus side it has a laser engraver so I could use photo resist and possibly engrave it then etch the board traditionally. This looks like it could be a pricey hobby, cos I bet once I build my first one, a better 2nd, 3rd will no doubt happen.

    Has anyone tried the Arduino zero? More powerful than an Uno, pricier too

    With 1 arduino uno you can drive 2 fans perfectly
