Create a timer clock for don't forget to stop

Hello all,

I bought an Arduino and Elegoo starter kit.
I want to make a clock on the LCD screen with an audible warning so that it can strike at specific times during the day to allow me to remember when it is necessary to carry out certain tasks of my daily life because I tend to let myself be surprised by time and forget to stop ...

Alarm clocks such as can be found on the apple watch (for example) are not bad but I do not have one and I would like to display it on the wall and that a light can indicate to me (in addition to the signal sound) that it's time to stop.

I do not know if it is possible to make a programming so that this reminder can warn me from Monday to Friday and 4 to 5 times during the day.
I would very much like to fill in the program that for example on Monday it can ring at 9 a.m., 10 a.m., 3 p.m. or even 6 p.m. and that on Thursday it is at different times than on Monday. Also, my schedules change over the months and it would be great if I could change the schedule daily and I could upload it weekly.

Is it feasible? could you advise me and help me to realize this programming?

I am thinking of going on the Tittiamo program shared on arduino.cc

Does this project seem feasible to you? isn't just the programming that seems complex? Can you guide me through your answer? Thank you very much in advance for your help!

Haha. What You ask for i built in my Pc 30 years ago. Repetitive reminders are kept in an auto reload file that transfers action to the actual calendar file. Then the calendar file is displayed the first I start my home application.
Involving time is no problem but calls for a real time clock, an RTC. One issue might be the memory available for the events. The repetitve actions needs storage as well as the single events You might want to add to the list.

No idea what that is! :confused:

Get a DS3231 RTC module to get the times right. It has an alarm function which can simplify your programming somewhat.
