Another one of our projects for our class is Arduino. We all got an Arduino kit and its basically a beginners guide to coding that's what I think of it as. You code this Arduino to do certain things like to blink its light or to make a sound, but you have to make the Arduino do that by putting the speakers on it and the wires on it etc.
This is one of my Arduino projects. This is the spaceship interface and what it does the lights on the board lights up.
