ow ow!! you are going too much into that very early. I tested it with led blinking (instead of watering) for example.. I connected the USB, then uploaded it. The program loaded correctly (coz i saw LED blink after the time i specified (in timer interval for repeatme). then i just removed my USB cable, then connected a 9V battery. Arduino got power, no other work is done. When i upload anyother program(LED blink in example program like that..), it works fine..
is there anything to do in extra to make it independent of the USB cable after the program is loaded???
if there are something, plz say that.!! i am new here boss. dont just say it wont load it wont load!! plz elaborate. I cant get you...
if at all some changes has to be done to the code, plz help me with that....
