I designed a alarm clock with rtc ic (rtc1302). Seller said that 1302 is no more avaliable in Turkey, these are last ics, you should use 1307 instead of 1302
But I used 1302. And add an alarm, sound plays with piezo sounder, and the melody of song belongs to a Turkish song; "ben sende tutuklu kaldım-by Sezen AKSU"
I hope you like it,and use it.
