Hello,
This is not correct:
import [processing.video](https://processing.video/).*;
noLoop() reference states :
Stops Processing from continuously executing the code within **draw()
I commented this out.
A serial connection may reboot Arduino (depends on the Arduino; watch for this) and I always add a:
delay(1000);
at the end of setup.
I moved:
//println(myString);
to the serialEvent() so it only updated when there was a serial event.
You should format code before posting:
https://discourse.processing.org/faq#format-your-code
- The double spacing made this difficult to read.
- Processing and Arduino IDE have an Auto Format that can be used.
It worked here with my video after I made changes above.
