Can you help me fix my code! When the $*$ is pressed, the code is suppposed to go into set mode. And during set mode, the hour, minute, second, am$/$pm$,$ and temp are to be updated. I need the coding solutions to my code not explaining to me what I need to do$.$ I$\text{'}$m using a nucleo board, $16$x$2$ LCD, potentiometer, and LM$35$ temp sensor$.$ My code is below!

#include "TextLCD.h$"$
