Is it bigger than a Breadboard?

Short post today... I'm sharing with you some of my work using breadboards and arduinos on 123d.circuits.io.

Simple Project

The first example is something simple. The light turns on when you press the button.

A little more difficult

This project isn't quite finished.
My intention here was to create a game where the Arduino would generate a random sequence of light flashes. You would then have to press the buttons corresponding to the lights in the same order that the lights flashed. The difficulty would increase as you went on.
Unfortunately, I couldn't quite get the software right. I had a hard time capturing the button presses, sequencing them, and matching that sequence to the true pattern. With a little more time I could probably get it working, but I welcome any comments!
