Digital Sound / Bell Timer Announcer

[Jawed Iqbal]

Hi Friends,

Works on Arduino & similar development boards, quite interesting and enjoyed.

Want to design & develop a Digital Sound or Digital Audio Announcer system with predefined Time triggered Announcements as in school or similar places.

After some search for the ready made product with similar features, found this product, as attached details.

The listed features in the attached product details are quite fascinating, but I want to make it low cost and with less features;

Do anyone here on this FORUM works on the same or similar DIY project based on ARDUINO boards?

Or any other MCU for the same project.

I will appreciate if someone can share his/her experience in the same design.

Regards to ALL.

I think for this type of smart projects, you must choose STM microcontrollers. With Arduino, the nearest thing I could find is this one: 

If you just want to make simple Arduino-based school bell, you can follow this design:
