We've started working on small Arduino projects, tutored by one of the founders of Arduino.
This is a small game made by using an Arduino board, 3 sentiometers, Arduino software and Processing.
Another small project I did with a friend. Connecting a led light to a DC motor, which makes the led spin around. On the breadboard we connected two light sensors, which turn two servo motors on and off. Because the LED light spins around they get turned on and off separately. The idea was to recreate a wave, but the DC motor was not strong enough to spin the LED slowly, so the result ended up being more like a thunderstorm.
