nice work but as for me i can not dive deep because i have other electronics interests my aim from processing programming is to make controls with Arduino and microelectronics

i can learn from 2 or 3 example of certain point if i stuck with some issues, if i couldn’t i ask here and there is a lot of good guys willing help

but I getting wrecked a primitive polling of devices.  
.  
Serial.list (this) [0]  
.  
I put the library well, in manual mode, through dfx .  
.  
-glv- wrote that he also did it on the phone. but he did not indicate which library he was using.I have provided an annotation and a direct link to the library that I used. in my previous post. but I do not understand this library is needed, or another.

Do I need it, or do I not need to install it additionally?
