Hello, I dont know what I am doing wrong but display is showing nothing... I connected everything precisely as you did, I can change brightness with potentimeter, but I cant see any numbers...
how to change duration of alarm? I want it to beep for like 1 sec, but i tried to change every number and it started to make only different sound...
