Five inch 7 segment display help
hello, I don't know how to run this on my project. the project is a simple esp32 driven traffic light system, esp32 was used for wireless sync between 2 units. anyways, i wanna use these as countdown timers, but can't seem to make it work. i use a 12v battery to power my system, with a 12v to 5v converter for the esp32. thanks
