Arduino and Processing

Many of the tutorials out there have lots of unnecessary code and don’t explain the basics of connecting the Arduino to Processing very well. This tutorial hopes to make it super simple.

Arduino ⇨ Processing

This tutorial has the very basic code needed to send data from Arduino to Processing.

• Arduino to Processing

And a slightly more advanced example of sending data from Arduino to Processing.

• Arduino to Processing with Photoresistor

Sending multiple values from Arduino to Processing

• Arduino to Processing with Multiple Values

Processing ⇨ Arduino

This tutorial also has the very basic code needed to send data from Processing to Arduino.

• Processing to Arduino

And a slightly more advanced example of sending data from Processing to Arduino.

• Processing to Arduino with 5 LEDs

Processing ⇔ Arduino

Sending data in both directions simultaneous is as simple as combining both of the basic examples from above.

• Processing & Arduino - Bi-directional
