about serial communication, and think about the possibiltity to use a end of message character, so you know when you read the serial port, where the message starts and ends. Let's way that the arduino send 2 messages while the computer is doing something else (like acquaring images) and then your serial port will have 2 voltage readings concatenated or half of a message then your data will be lost.

You were right. I needed a different parallel loop. Now it works perfectly. 

Many thanks, you saved me 😉
