Hi There
I am trying to setup a device for setting a reminder for my son medicine, the functionality would be if we give him medicine then press the bottom which turn light to green if we forget to give medicine by 10PM then it will generate an alarm , he has a rare.life threading disease where he must have medicine at specific time otherwise he will go into coma.
here is the code I have done, the light works with bottom but the timer not working
can someone help please
regards
Adam
