Mechanical 7 Segment Display Clock Using An Arduino 28 Servos

In this project, Ill 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 Arduinos PWM IO over the I2C interface.
