today i build the schematic and the pcb for init_dawn.d , it took me likely 3hr and 30 minute but due to some lapse problem i cant sync it , anyway i added only 7 physical switches because i dont need 12 , i used 5 gpio pins for the 7 switches , i have a proper idea to control them by using separate mode , 1: Configurable mode
2: Alarm mode
i mean when config mode , the bottom 5 switch will work and when alarm mode only upper two . Also the bottom right is kinda a shift switch , to change +/- for hour and minutes etc , its still a draft but the idea looks clean.
