How to make a 5 minute timer circuit?
So to build a 5 minute timer circuit, we would be simply changing the resitor value to 272.7k ohm in above given 1 minute timer circuit. Similarly to create a 10 minute timer we would be changing the resistor value to 545.4 k ohm. As per above calculations, for a 15 minute timer circuit, we need the value of resistor to 818.2k ohm.
What do I need to make a buzzer timer?
You may not be allowed to use an IC 555 timer, but you could just breadboard one yourself. As you can see, the main components you would need are a couple of comparators, an NPN transistor, and an SR flip-flop. The output driver would basically be another transistor which you would use to drive your buzzer circuit.
