Arduino Open Source X-PID firmware incl.360°option

As former explained you can connect as much arduinos as you like, but he is talking about one arduino and three axis.
For your bridges is no coding needed, they are used in the pictures.

Hi Sirnoname,

Thank you from me too! I'm still before investing the money into motor driver electronics. I'm really interested in you arduino solution.
I've looked after the boards on ebay. Unfortunatelly the 43a single and the 60a dual h-bridges labelled as not shipping to Hungary. So I found the "Another dual bridge with 68A from the ebay shop 1984yht888". This has also a cheap price (16.87$) .
But, and now comes my question, I'm not sure if it can really drive two motors. I've never used h-bridges before, but from the picture it seems it has also 4 ports (at the green connectors), just like the single one above. As far as I understand there're 2 ports for current (+ and -), and two for the motors. I've no problem ordering two of them, just want to be sure.

Thanks and regards,
Tamas

Hello BobBuilt,

Here it is:

This is the third picture at "H-Bridge reqirements:" in the first page of this thread.

In China a 1,2GHz tablet comes with a 800MHz main CPU and a 400MHz graphic CPU. They combine the MHz to 1,2Ghz tablet. However it is slow because it is only a 800MHz tablet.
Same with H-Bridges, I think a 60Ampere double H-Bridge can handle 2x30Ampere. I have seen some guys which have connected the power sources together and use for one motor both H-Bridges on a board (and same control pins for both bridges). I do not know how save this is? Perhaps someone has some experince with this?
Buying exact the amount of H-Bridges that you need will make you trouble because they get very soon unknown and inavailable. If you damage one of them you have to wait for the next one.

Result: You cannot have enough H-Bridges

It is not "Dual H-bridge" module. It is ONE full bridge, based on two H-bridge drivers BTN7970 - Edge

One module can control only one DC motor

And you can't connect this module directly to Arduino with Sir (or mine) firmwares.

Thanks! Yes, it was suspicious that it can drive one motor only.

The arduino can handle even 6dof Looking at this site:

My Arduino is ordered

what video?

As said a nice found.
The document has a copyright, is there a link for this document that we can exchange to your upload?
Or are we allowed to use it?

It could be a dream to own a 6 dof platform ! but it could turn fast into nightmare when we try to introduce a classic washout filter and/or predictive algorythm It is very difficult to fight against parasite force !

I thing the best type of simulator for some people and me are those they works with proprioception = Simple, compact, less expensive, accurate...

Of topic but a very good document!
