This section is designed to teach the basic principles of LED wiring and usage, as well as to provide an introduction to electronics and the electronics setup of the Arduino + LEGO Robot.
In order to complete the projects in this section, you will need: - LEGO+Arduino Robot Base with DFRobot Motor Shield
- 2 LEDs (preferably Red, but the examples also use Orange LEDs) - can be found at www.sparkfun.com 
-At least four Jumper wires of various sizes and colors - These can be found anywhere, but the ones used in the examples came from www.sparkfun.com 
-2 470Ω resistors - again, my be found in many places, but ours are from www.sparkfun.com  (The sparkfun kit contains a large number of resistors of various types to suit any electronics projects you have in mind)
