Pinball style Clock

This is my project for the bambulab clock contest.It is inspired by the scorewheels of electromechanical pinball machines. The clock is using 4 score wheels mounted on 28BJY-48 Stepper motors for displaying the time.When setting up the clock, it has to be homed. Therefore the homing button needs to be pressed around 5s. All 4 wheels will drive to 0 position.This will also reset the used RTC to 00:00.The time can be adjsuted by holding the Set button for 5 sec.Afterwards the time adjustment is happening by pressing the + button. with the Set button you can switch between the wheels for the setup.After adjusting the last wheel, another press on the Set button will bring the clock back to operating mode.There are 6 different LED Modes also brightness can be adjusted in 3 different modes (low, medium, high). I split up the code on 2 arduino (1x for logic 1x for driving the stepper). Following electronic components are needed:2x Arduino Nano1x RTC Module DS32314x 28BYJ-48 Stepper + 4x ULN20
