I'm working on a robot balance project. I use an arduino UNO with the 6DOF shield from DFRobot (http://www.dfrobot.com/wiki/index.php/6_Dof_Shield_(DFR0209)). I just use accelerometer and gyroscope and this shield. My question is :
I programmed my code without problem, actually it works when I kept my USB connection. But when I want to use my board without USB connection it doesn't work. Is there a protocol issue or something like that?
Despite, I put the arduino example "Blink" on my board it is exactly the same problem. It works without the shield and doesn't work with.
Thank you very much for your help,
