That is normal for Arduino boards.
ok thanks You could always Google for some various methods of disabling this auto reset 
Just be aware of the consequences as related to seamlessly uploading code.
That’s another reasons why Arduino’s are on THE LIST.
Come the glorious day …
That’s not a fault in the Arduino, it was designed that way to facilitate easy uploading 
You mean the list of things that Gunner likes becasue they still work, are adaptable and fun to make things with that prove others wrong when they say Arduinos are only good for blinking LEDs… a common quote from a robotics product developer whom I quickly lost all respect for, due his arrogance and attitudes towards others and against anything he didn’t make himself 
- Ironically, it was his distaste for Arduinos that fueled my search for ways to use them with minimal programming… and that led me to Blynk… and to learning to program anyhow particularly so I can blink many LEDs
