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

[trust928]

this card is home made... so i think thats it... ima gonna buy a sabertooth 2x12 its really expesive here in brazil its like 150 dollar but thats the way theres nothing to do..

the sabertooth 2x12 can connect easy with the arduino r3 right? just plug and play with the x-pid firmware? i need to know coz im not rich to given money alway lool

thanks to all help

[trust928]

the card in it self can handle 12v 40 amps..

its got inA and InB HE SPINs to either direction with 5v it goes foward and backward,, so i thought its was gonna work its so cheap to build.. and can handle 40 amps.. if some one know how we can resolve it.. its was going to be the chepeast hipower hbridge

This can be done with open the pot and paint the not needed slider way with electric leading paint (Pot hardware mounting, page1)

Thanks, great tip! I now have much smother feedback values and as a side effect better, more robust pots.
It's really worth fiddling with the pots and modifying them according to your instructions.

Can I use this board to drive wiper motors?

Or maybe this board can be programmed with sirnoname firmware:

It looks like it have all-in-one to build a 2x15A DC motor simulator.

My regards!

Do you know why they refer to that Monster board as a moto shield?

Maybe the issues you have are because it uses the VNH2SP30 full-bridge motor drivers... Not h-bridge like the L298.

Hi,
@ trust928

**the sabertooth 2x12 can connect easy with the arduino r3 right? just plug and play with the x-pid firmware? i need to know coz im not rich to given money alway lool **


I used two sabertooth 2x25 and it don't works with XPID unless you CHANGE the firmware to use the sabertooth in 0-2.5-5volt (full backward, stop, forward) you need a lowpass filter to the PWM output of arduino. Then 2x12 should produce 12amps continuous and 40 peak (a few seconds)

The cards Sirnoname board tips are much less expensive and works.

Sorry but I am not an electronics expert so very often I get lost.

So to be clear, is this one ok to work with arduino r3?

Thx Bob!

Hello Sirnoname,
i am going to build a system based on your ideas in this thread. Thanks alot for your guide.
But i still have some question about choosing the right pots.
Is it correct, that you use pots as a so called "unbelasteter spannungsteiler" (unloaded voltage divider, is this the correct word?)?
Does maximum load in Watt matter? Most pots have max load from 0.2watt to 2watt, some pots have even more.
Is it correct, that you should prefer high ohm pots for minimum noise?
You wrote in your guide to choose any pot from market between 5kohm and 100kohm(47kohm standart). Some people recommend a 5 or 10 kohm pot.
I am still unsure which pot to buy. Hope someone can point me into the right direction.

greetings

edit: spend some time on research again. Maximum load(Watt) for pots does not seem to matter when using pots as "unloaded voltage divider".
Choose pot´s Ohm as high as possible. Can someone please confirm this?

Can you please look if the following dual h-bridge

is compatible with this topic's Arduino solution?

Yes, It should be work, I agree with Sirnoname.

Hello!,
I just got this motor driver
http://www.ebay.com/itm/160954041846?ss ... 1439.l2649
which should be the same one as mentioned by wptm and been "certified" by prilad and sirnoname

I am trying to connect the wires to the arduino uno right now,
but there are only 4 pins on the driver (besides 5v and ground)

Is this really usable to control the L and R motors separately?
or does it drive 2 motors in the same direction (like car wheels), using a single input?

Will i need to get another driver card?
The meaning of "dual" is confusing me like hell
