I have a sketch, which runs without issues, when i start it while the PC is connected. I have some serial outputs and everything is fine.
Then i have removed all the serial prints and transfer  the sketch to the arduino in order to run it without the pc.

It does not work? Can you please help!!!

how are things powered ? and (important) make sure grounds are connected between your board and external devices

Please correct your post above and add code tags around your code:
[code] // your code is here [/code].

It should look like this:
Code: [Select]
// your code is here
(Also press ctrl-T (PC) or cmd-T (Mac) in the IDE before copying to indent your code properly)

Hello - Please do not PM me for help,  others will benefit as well if you post your question publicly on the forums.
