60flaps * 2drums split flap display clock

How it Works: 1. Arduino moves the 28BYJ-48 stepping motor based on the time provided by the Real Time Clock. 2. The right drum moves one step per minute, while the left drum moves one step every sixty minutes; each drum is attached with sixty plates. 3. With a photo reflector positioned in the drum, Arduino accurately determines the absolute angle. Improvements Made to the Four Digit Split Flap Display Clock: 1. Reduced the number of motors from four to two for improved efficiency. 2. Eliminated the need for gears by coaxially arranging the drum and motor. 3. Concealed wiring within the frame for a neater appearance. 4. Altered the position of the infrared sensor to minimize the influence of ambient light. Printing Number Plates: It is labor-intensive to manually paste number seals, taking me an entire day to complete. However, if you have access to a dual-nozzle printer and can create 3D data for a plate with numbers, you can effortlessly print it. Arduino Source Code and Schematic Upload: I have uploaded the Arduino source code and schematic files for your reference.
