Hi all..
I'm designing a Safe deposit box..
It use motor to open and close the box..
but i want to know if the door is blocked when closing/opening..
I realize that the current needed for the motor will increase if it's blocked..
I'm using ATmega ADC, but it need voltage input..
so i need a current-voltage converter to know if it's blocked or not..
can someone provide me with circuit and explanation?
thx
Daniel
