Flip Clock v2 - Arduino-Powered Split-Flap Clock

For the latest files and updates, refer to the GitHub page: https://github.com/alexyu132/flipclock Finally got around to completing my flip clock design. Compared to the original version, this version now has mechanical endstops on its displays for greater reliability. Driver code is now provided, as well as a full BOM and assembly guide. Flip Clock v2 Arduino-powered clock using split-flap mechanical displays. Features Automatic time setting on sketch upload RTC module keeps track of time even when unpowered US DST support - clock automatically skips forward/back 1 hour as needed Runs off of Arduino's USB power - no separate power input needed Automatic calibration once per rotation using mechanical endstops Steppers turned off when not moving for power savings Non-printed parts | Part | Quantity | Notes || --- | --- | --- || M3x10mm button head screw | 17 | || M3 lock nut | 17 | || 28byj-48 stepper motor | 3 | || ULN2003 stepper driver | 3 | || Pro Micro or similar small Arduino (5V)
