I am using Arduino atMega 2560 for my Project.
I am writting program in Arduino IDE under LINUX.
I am successful in controlling Arduino through USB programming.
I came across an issue that is I do not see output on GPIOs if I do not turn on the Serial Monitor.
But if I open the Serial Monitor Screen I am able to see the outputs on GPIOs.
Finally in the Application I do not have freedom to turn on the IDE always.
Please let me know how to overcome this as I need to see the output even if Serial Monitor is off.
