+HELP: FINDING THE CORRECT USB PORT
+if you can not find your arduino USB port, make a new file and add this code:
+* CODE START *
+import processing.serial.*;
+// List all the available serial ports
+printArray(Serial.list());
+* CODE END *
+It will print out a list of all your USB connections.
+Find the [ ] number for your Arduino Port and include it in line 8 of this code.
