Buzzer for Hot Water with 10 min timer Answered
I want to make a 220v buzzer with timer 10 min.
My thought is to control my electricity bill by reducing water heater usage.
This buzzer will help me remind me that water heater is on for 10 min so that I can switch it off to save power.
I know it is seemed to very easy for pro guys but very difficult for me.
Please help me understand and make such buzzer with minimal budget.
I need help to make this project.
Kindly let me know how can I do it.
