Sorry, but you must follow my connection diagram using a common anode LED display. Otherwise, you must change the code according to your hardware.
Thanks for the feedback, Brian!
Pls, keep me informed about your progress and publish a picture of the clock in a case.
Happy new year!
You should use power transistors to control the LEDs and a power supply corresponding to high current of circuit you need.
