test arduino IDE, it makes /home/pi/sketchbook   !close it again
copy arduino /home/pi/PMS3RPIv3/arduinosketch/PMS3RPI to /home/pi/sketchbook
run arduino IDE again and find PMS3RPI sketch
adjust |tools|board|(MEGA) and |tools|serial port|
upload
better not try the arduino ide terminal on that data stream
