speaker with timer

[Dharam Nath Roy]

Dear Sir, 

I want to make a circuit which will connect two sound system. one sound system will paly for four hours and will automatically turn off and switch on the next sound system. and this will continuosly play .

[Ashutosh Bhatt]

you need one AVR micro controller like ATMega16

one IIC based RTC – real time clock

and two relays – to switch on or off any speaker system

 

program the RTC as per your requirement. it can give alarm signal similar to normal alarm watch. so you can set alarm as per your convenience like 4 hrs, 5 hrs, 6 hrs etc

 

to program and control RTC you need AVR micro controller. follow the AVR and RTC tutorials on

EG labs / micro controllers / AVR on this site

Thanks for the comments. The purpose for this speaker is to play  some mantras continuosly even without interupting for a second. I want to use it in my house so that my house will continuosly radiate +ve energy. And the house where these mantras are played continously is capable of healing any disease , and the mind of the people living in such a house will remain cool and they will feel happy at every moment.
