I wrote a sketch. Verified it. Downloaded it. All no problems. It drives my robot and uses a Ping to look for obstacles.
Tethered to the USB cable the Ardweeny seems to run the sketch fine. Both motors turn, I can see the Ping sensor working, if I put my hand up as an obstacle it changes the motor spin to turn away. Very cool.
If I take it off the USB and switch on onboard power, the Ardweeny runs something else. One motor always on, the other cutting in and out repeatedly and the Ping isn’t on.
I don’t get it.
No errors. No feedback. Just not the expected behavior. About wore out the reset button. Why would it be different?
Any ideas? :-/
