In this video I explain how to connect LEDs to a Raspberry Pi’s general purpose input-output (GPIO) pins, and how to write Python code to turn them on and off. My next video then builds on this foundation to control a motorized robot, and can be found here: http://youtu.be/AZSiqj0NZgU
This video assumes some knowledge covered in my «Setting Up a Raspberry Pi» video: https://www.youtube.com/watch?v=U7Dj7R8bu4k
Note that this tutorial will work with both a Raspberry Pi Model B, as well as the newer Model B+ (on which I will do a video shortly!).
You can find the wiring diagrams, as well as links for the components used in my Raspberry Pi robotics videos here: http://explainingcomputers.com/rasp_pi_robotics.html
