Dear all,

I am new of this kind of things, sorry for the strange question in advance...

I connected an Arduino MEGA with another board. Arduino is my slave and receives a char from the master.

On my serial monitor I can see the correct value but at the end I always get value 0, like;

12 0
1 0
4 0
23 0

12,234,1,4,123...are the values that I send to the Arduino, but what is the 0?
Some one can explain me why?

Thank you

There is something wrong with your code.
