so all i wanted to do was with a nine volt battery a buzzer an LED and a mini momentary push button switch. but i was wondering how to make the buzzer and light flash/ beep on and off when the switch was pushed. I don't have any fancy IC's and i only have about 3 days to do it. Last i would like to know if i would have to add anything because the buzzer is a 12v and i am using a nine volt battery so by adding other components it almost silences the buzzer so what do i have to do with it to make it work well?
