Talking Clock DFPlayer LCD RTC
The clock uses an RTC module for the time, a DFPlayer to play the mp3 files and an LCD to display the time and instructions. Buttons functions are: Hours +, Minutes +, Choice of bell, Choice between bell and voice, Say the time on request. There is a link to my web page, but it's in French...
Power supply 220V 5V or external power
1 micro SD card
1 LCD 2X16
Resistors 6 x 1 KOhm
The project is pretty straight forward just a lot of wires !
I gathered the resistors on a prototype board, as well as the nano, RTC and DFPlayer on another prototype board.
The housing is a broken Alarm Clock.
Just put the mp3 files on the SD card, follow the files naming. The list of required files in given here. Please note that in my example, I use three different bell tones. You may put your own or have even more, but you'll have to modify the sketch.
