Challenge Review
In this challenge, you will program your EV3 robot to through three different intersection, each of which has a traffic signal. The traffic signal, which can be either the colored block or the red/green card, is held by hand at a set height. Unlike a camera, the detection range of the Color Sensor is short, so you will need to modify its placement on the robot so that it can see the traffic signal and react appropiately.
The robot does not need to stop on its own after passing through all three intersections (it can be stopped by hand).
Bonus: Write the program so that it DOES always stop after going through the third intersection. This will require the use of a Switch (see next section).
