Serial Communication with Processing :: Video #2 :: Arduino Serial Communication Series

This tutorial guides you through setting up a simple communication between an Arduino and a Processing sketch. It covers the necessary components, circuit setup, and coding in both Arduino and Processing environments. The tutorial explains how to use a push button to send data from Arduino to Processing, which then visualizes the data by changing the color of a square. The video concludes with a demonstration of the project, highlighting the ease of integrating Arduino with Processing for interactive projects.

What components are needed to set up the basic circuit for Arduino communication?

• Arduino, push button, resistors, jumper wires, breadboard
