Hi

my device will be in sleep mode always and wakesup when there is an interrupt.

Now i want to make arduino pro mini reset using hall sensor. if hall sensor is contacted with magnet more than 4 seconds then device should reset.

Is it possible to do?

can someone please help me

Using an NE555 and some external part this should be possible quite easily. Use the timer chip to activate a transistor to pull RST low. I never tried it myself though.

How do you propose to keep the Arduino from immediately going back to sleep?
