Communication is an important thing that is widely being used to share information. We, humans, are communicating with each other using various mediums. Not only us, everything in the universe have a way to communicate and transmit data from one place to another.

Most of the people who are in love with ESP32 or Arduino things are just preferring Processing to create GUI. There, you can handle almost all the things without** editing** your Arduino sketch.

What for Java people? Even though** Java people** use various IDE to create various magnificent things, should they get defeated by this communication issue?

Hey wait, are you kidding me? Processing and Java, are they different? When you are using Processing, at your right top corner, you can see mode selection, and most probably you can see Java. Then your face will probably shine and start coding public class bla bla and so on….!

Yes?

Hell no.

Just look at this example.
