just makes the question a bit clearer and more specific, i clicked on thinking this question was regarding powering the arduino from the wall instead of the pc.

| Nov 17, 2014 at 9:33 | comment | added | Mr. Robot | probably you were right. If I disconnect all sensors from arduino, the DC motors are making some motion... they're really slow but they are moving. | |
| Nov 17, 2014 at 9:15 | comment | added | Mr. Robot | Yes, It really has 9V. I have 2 same 9V batteries. One for DC motors and one for arduino. DC motors are working properly with this battery but arduino is not. | |
