Hi all
I wish to make a device with 89C2051 where I have to start a motor and atop it after 30, 60, 120 or 180 minutes based on switch selection.
I have never seen any application that demands such a long interval.
What is the best way to achieve these intervals and what are the pitfalls in making the controller execute such a feat?
Any help will be greatly appreciated.
TIA
