Arduino Inventor’s Guide CIRC-04 (Servo)

The fourth circuit from the Arduino Inventor’s Guide controls a servo. Servos can be positioned from 0 to 180 degrees, and this positioning is controlled through a timed pulse.


Arduino CIRC-04


  • 1 x Arduino Duemilanove
  • 1 x Breadboard
  • 1 x Mini Servo
  • 5 x Wire

Additional Resources:

This circuit was really easy to wire up correctly and was also a lot of fun to see in action. I recommend playing around a bit with the code, changing delay and position values to see what effect it has on the servo. I think this will end up being a very useful component in future projects.
