vespapierre:
I will try, sorry for my english. So I'm just arround on a beginner level ( I guess) in programming with Arduino. I have tried to merged the setup and loop parts. After I have tried to remove the serial.print -s as much as I can, not to use float-s but the sketch size was arround 34K.
I fail to see how a 34K sketch size would be considered "small"
I also fail to see any code that shows how you tried to merge them.
