So according to scheme i need 4 jumper wires and 8 classical ? dfrobot.com/wiki/images/thum … 0002_6.png
i have found sth in my country is it right ? - elektronicke-stavebnice.heureka. … -bal-10ks/
Not too likely
What you found in your country is correct.

So fro actuators i need 4 classical cables 4 jumper cables to connect motor controller and microcontroller,
About other cables it seems like there should be 4 jumper cables with female connector cut and connected to batteries and motor controller , also 2 of jumper cables are in one pin so can i cut isolation from jumper cable and connect there the cable that should go to the same pin ? I knew there is something that can connect them both but im not sure that i can get so would it work if just cut them and connect like that ? I hope u understand what i mean. I can draw u a scheme if its needed 
Don’t worry about specific wire types so long as they can plug in correctly. Just ensure the connections are good.
okay ill connect everything and send the pic of it to make sure its ok then we can continue with programming
Hello we have made a lot of work but always some problem appears. Stabilisator on arduino bluno got damaged so we changed it to stronger one we think it was because of high voltage 5V from usb and 9 V from batteries and arduino is for 12V
Or maybe it was because motors are higher current that has arduino
All said we had programmed it but now we have issue bluno module on arduino bluno doesnt want to work can u help us ? I hope its not damaged or something
The Arduino cannot be used to power the motors directly. One of many things may have gone wrong, so the only way we can troubleshoot is if you provide a clear wiring diagram of the entire setup.
When you say “not working” - what are the symptoms? Have you tried the Bluno on its own?
My friend has all the electronics so he can tell u the exact things. He will write here later. I remember only that we programmed everything, wwe coudl control it by pc. WE later tried to set it up by bluetooth. We could pair bluno and smartphone, but when we got to app it wouldnt let us to connect to it in the app.
Also here is hte photo of our system how we connected it (the only thing that we have changed was adding switch on the supply), however we think the problem is somewhere in the bluno not the connection or code, we would appreciate every help.
Can you disconnect everything except power to the Bluno and try to upload simple code (Blink for example). You need to determine product by product which works and which does not.
