A lot of people find it easier to fall asleep with a dim light such as a nightlight in the room. But the down side of most nightlights is that they waste electricity because they are on all night when you really only need them to be on while you are falling asleep. So I […]

At BeatBots, we believe that dancing is one of the most worthwhile occupations a robot can have. We like making cute characters move in interesting ways, and as you’ll see, this doesn’t require expensive components or complicated programming. For Spazzi here, we decided to forego the rotational motors (servos and steppers) that many robots use. […]

This simple project uses an Arduino, a photoresistor, 2 potentiometers, and a resistor and uses basic serial communication between the Arduino and your computer. Basically, the user can draw by controlling two potentiometers (drawing knobs) and the photoresistor determines how dark the circle will be drawn.

In this project, we’ll build a small, vertical-axis wind turbine, or VAWT for short. These are not as efficient as their horizontal-axis cousins, but they are better suited to urban environments where wind can come from all different directions. Normally, when you give electricity to a motor, it spins. The same is true in reverse: […]
