Arduino Basics

In this project, I have connected an Arduino to my computer and used a photoresistor to control an animation on the screen. Other sensors could have been used, but I chose a photoresistor because it feels like magic!! The photoresistor responds to changes in ambient light as my hand moves up and down. The Arduino sends the reading to a Processing sketch on the computer via a Serial command (through the USB cable). The processing sketch interprets the signal from the Arduino and selects the appropriate picture to display. I took a series of screenshots from the following YouTube video:  http://www.youtube.com/watch?v=h6nE8m74kDg   And after borrowing a bit of code from these sites ( 1 , 2 ), the project was born. This idea is not new, nor my own. There are many people who have done this project before, but I thought to blog about how I have done it, just for fun. The Project Movie Components Required Arduino Uno (and associated software), and USB cable Photoresistor ...
