Arduino serial monitor and java resets variables?

Arduino's reset themselves when you open a serial connection to them through for example the serial monitor.

The initial state of the led is off. For some reason it seem that Arduino does reset itself when I use the dev environment or my java test app but not when I use C#. – Petezah Jan 23 '10 at 11:58 Figures; maybe the Java and Serial monitor close the serial connection and the C# app doesn't?

Fact is that your arduino needs to reset before being able to send/receive serial data. – fijter Jan 24 '10 at 12:38 2 Put a simple bit of code in the setup() part of your program on the Arduino - make it flash the LED twice (and leave it in the off state afterwards). That way you can know it has been reset and that you main program is ready for input... – Alan Moore Jan 25 '10 at 13:56.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
