Mechanical 7 Segment Display Clock Using An Arduino & 28 Servos

In this project, I’ll be showing you how to build a mechanical 7 segment display clock which is driven by 28 servos controlled by an Arduino Uno. Time is kept using a DS1302 real time clock module and each servo is independently controlled using two PCA9685 16 channel servo drivers to expand the Arduino’s PWM IO over the I2C interface.

For a detailed write-up on the build and further description of the code & 3D print files, have a look at the full build through this link - https://www.the-diy-life.com/mechanic...
