Three dozen servos create animated artwork
Servo motors form the basis of many Arduino projects, but few use them in as interesting a manner as Doug Domke’s piece of electronic art.
The device features 36 servo motors arranged on a pegboard to produce various patterns, and can even be used in an interactive mode where it follows a person’s hand around with the help of ultrasonic sensors.
Everything is driven by an Arduino Uno along with three 16-channel PWM control modules, and popsicle sticks show the servo movement to onlookers.
Details, including Arduino code, can be found in the Domke’s write-up. To really appreciate this project’s visuals, be sure to take in the coordinated movements in the video below!
