Summary

  • A sliding tile clock made by hacks uses an Arduino Nano ESP32 to control four stepper motors via a ULN2003 IC, to create a unique time display.
  • The ESP32 connects to the internet through its in-built WiFi to synchronise with time servers for accuracy.
  • The 4 digits of the clock use number tiles that slide into place as each digit rotates.
  • Each digit can be incremented by turning 180 degrees for the next number to be displayed, hauled into place by the stepper motors.
  • All the custom parts of the clock were made through 3D printing.
