Oh, I'll try my best, thanks.
If I try:
Motor(-120,120);
delay(200);
Motor(0,0);
delay(200);
Motor(120,-120);
delay(200);
It resets after doing the loop once, if I plug in my USB cable while the battery is in as well, this does not happen and the board continues to operate. But if I unplug the USB again (battery power only: 10.5V), the board does void setup (), but resets after finishing. So it does void setup over and over again.
This only changes if I unplug the battery, and rewrite the code to the board.
Also, am I supposed to connect my board to usb and battery at the same time? The battery is connected to Vin(+) and GND(-).
Thanks so far
