I have a sketch that talks to an Arduino. I would like it to stop and warn me when the arduino is not present so I tried: void setup() { size(1900, 950, JAVA2D); printArray(Serial.list()); if (Serial.list().length > 0) { serialConnect =true; myPort = new Serial(this, Serial.list…

Conditioning the sketch on finding the COM port trouble

This is just one.

I used to run a script to do this.
