hello
i bought this 4 digit led display (it haves a tm1637 chip) to display a timer and im experiencing some problems with it. when im connecting it to the arduino (Uno) 5v output it doesent works properly - the time doesn't "refreshes" and im stuck on " 00:00". but when im using the 3.3v pin it works perfectly.
the problem is that i need it to work with my 5v pro mini.
anyone have a solution for that?
i also attached the code im using
