I haven't tried that yet. Edit: I just did it, I set (voltage == LOW_BATT) and it fixed the issue.

The switch was set to Arduino when I downloaded the software.

Yes I tried that but It didn't help.

I just measured the battery's voltage and it came out to 8.28V so I don't think that's an issue. I also tried to use the bittle through WriteInstinct.ino and it seemed to work fine, I could make it sit or stand. My guess is that there is some kind of problem with OpenCat.ino I might try reinstalling it again but It probably won't help.

I think it has been working for a couple of months or so. I haven't noticed any physical damage like smoke. I can still upload sketches to the NyBoard and they seem to work fine (for example the buzzer test). If you mean what is in output when I upload OpenCat.ino then I can send the whole thing here but it's very long. I forgot to mention this in the post but even if I connect the NyBoard via cable without the battery it still beeps that the battery is dead.

Yes, I did that, the bittle was working perfectly and could move and all of the other stuff but one time after it died I charged it back it and it still kept on beeping even though it was fully charged. The connections look good and I don't see any damage, the cable got a bit cut before but I was able to fix it and it doesn't seem to be the issue
