7 Segment Servo Motor Clock using an Arduino Nano & 3D Printed 7 Segment Displays Based on this clock https://www.the-diy-life.com/mechanical-7-segment-display-clock-using-an-arduino-28-servos/ See also this also based on the same clock https://www.thingiverse.com/thing:4846668 Full build info on my Web site here http://www.brettoliver.org.uk/servo_clock/servo_clock.htm A large (640mm x 290mm) wall mounted 7 segment servo motor clock using an Arduino Nano microcontroller to drive 28 servo motors via 2 x 16 channel servo controllers. A Wemos D1 mini ESP-8266 microcontroller provides FTP sync for the clock on 30 seconds and also drives a string of 60 LEDs (WS2812 60 LED strip). The 60 LEDs display the seconds as a backlight to the rear of the clock either as a single LED or 59 LEDs on with a single contrasting LED indicating the seconds.
