littleBits Servo
The servo Bit is something that we're really excited about - a controllable motor that can swing back and forth! It has two modes: in "Turn" mode, the input from other littleBits determines the position of the arm - try using a dimmer to set the angle you want. In "Swing" mode, the servo will move back and forth on its own - the input controls how fast it goes. Attach a flag to the arm to make a signaling machine!
