Yes. Because my lecturer needs the students to understand the basic logic gates. In order to understand, we need to separate each counter and each decoder

Well, I also need to display it by using 7 segments. Well, if I can make the sound at 10 minutes and 15 minutes, that would be great, but if I can make it just by a sign (maybe LED which acts as a sign), that will do the job

You mean by using two flip-flops with a time period of five minutes each will produce a buzzer? Heum.. I see that is no problem at all, but what I'm trying to do here is how to use a flip-flop, each counter and each decoder, to produce a buzzer at 10 minutes and 15 minutes

Thanks man, but my purpose here is to understand flip-flop and logic gates (which they are on my courses). I started practicing since last year which is my second year of college

I think I'm getting into this. You mean divide the 32.768 kHz by two which means change it into 1 Hz right? so it will produce a real time? Isn't? Why the 5 minutes instead 10 minutes and 15 minutes? Or is it the difference between them?

Yeah sure, it's allowed to use logic gates and use discrete transistors. Well actually I was told to use any type of flip-flop, a counter and a decoder which is not built-in IC (it's seperate, each counter and each decoder). I told you, I don't have any point to make this, but I'm pretty sure...

I need to make a digital counter circuit which it counts to 15 minutes for my big project in my campus . When the circuit counts to 10 minutes, it will rings a buzzer. Same when it continues to 15 minutes, it will ring a buzzer again. (the circuit is for public speaking, so the speaker knows...
