Electromechanical 7-segment clock made with an Arduino and 28 servos

From blog.arduino.cc 2 years ago in Platforms Stores

Digital clocks are often made out of a series of 7-segment displays, which light up to represent the needed numbers. Michael Klements’ electromechanical project, however, doesn’t use LEDs, but instead physically flips 3D-printed segments into view with 28 micro servos. When in use, each segment’s bright green surface is clearly...
