Welcome to the sixth Arduino Tutorial from our Arduino Tutorial Series. In this tutorial we will learn how to connect Arduino to Processing and how are they communicatng using the Serial Port. Also we will make an example where we will use the Processing IDE to send commands to the Arduino Board and vice-verse.
This is a Step by Step Video Tutorial which is easy to be followed. Also, below the video you can find what Parts do we need for this tutorial and the Source Codes of the Examples in the video.
