Using an RPi to Control an RGB LED

As rahulkar mentioned in his tutorial, LED control seems to be the “Hello World” of electronics. It’s easy to set up, you learn a lot about how electronics work, and in the end, you’ve got a nifty little piece of hardware to show off to your friends - and it’s pretty cool! This tutorial will be bare-basics, the idea being that you could use this tutorial as your first project in order to get a basic understanding of the Raspberry Pi, circuits, and programming. In particular, I will explain the code behind the program line-by-line for those of you who are new to Python. After this tutorial, you should have a grasp on how basic programs operate and be able to modify our code.”
