Grade crossing example using Arduino

In this episode, Jimmy puts everything together from the first two episodes! We prototype up a simple grade crossing circuit on a breadboard and write some Arduino code to drive it. Very cool!

If you'd like a bit more in-depth tutorial on using a breadboard, check out this short video on YouTube: https://www.youtube.com/watch?v=fq6U5Y14oM4
