Thank you for this fantastic tip!
I have only one question left.
How does it compile?
I have seen some code and it makes sense. But how do I get from writing the code to compiling and downloading it to the Arduino?
I know I am kind of lazy in asking this but it puzzeles me.
It seems to be the only obsticle for me knowing how to proceed.
But I guess this reveals itself when I have actually bought and started to use the fantastic Arduino UNO.
Best regards, Roger
