I made a GPS system and want it to be able to work on a 9V battery.
Everything works perfectly fine in the IDE but when I switch to my battery or connect it to my pc without the serial monitor open it doesn’t work anymore.
I searched around and found it was most likely the serial connection auto-resetting. But even when i implemented the resistor as was said to do here: http://playground.arduino.cc/Main/DisablingAutoResetOnSerialConnection
It still wouldn’t work!
Is this something in the code maybe? or something with the arduino itself?
BTW, using a mega AT2560 and followed those instructions.
