Learning Objective:
Build a robotic NXT LEGO car equipped with a light sensor and program it to drive at a speed based on the light sensor input.

Student Challenge:
Build and program a two-motor car equipped with a light sensor. The car should drive forward and will have its speed dependent on the amount of light detected by the light sensor.

Concepts:
Using Loop Block and Math Block.
Using Wiring to directly pass data from one block to another.

Extensions:
Adjust the math block to make the robot behave differently (i.e. move quickly in bright areas)
