Bringing Legos to Life with Code
Have you ever wished that you could bring your favorite Lego creations to life? Maybe not to life in the way that a plant or animal is alive, but at least to see them move across the room on their own, react to their environment, or even just to make a little noise? The Lego EV3 set allows us to do just that.
What Distinguishes EV3 from other Lego Sets?
For starters, the home EV3 set contains over 600 pieces, mostly similar to those in the Lego Technic line. However, it also includes a set of sensors (infrared sensor, color sensor, and touch sensor) and a “brain”. The brain is actually a small computer that connects to a laptop or PC with a USB cord and allows programs written on your computer to be downloaded to any EV3 project!
How Does it Work?
Through code, we can program motors to rotate at varying speeds, obstacles can be detected, and beginners as well as experienced coders can transfer their programs from a computer to a Lego robot. Although Lego created its own drag and drop language for the EV3 set, it shares many of the features of a standard, text-based, language. As such, when we program an EV3 robot we develop algorithms that include looping, conditional logic, variables, and math, and we can even write our own functions.
