SupeR-NovA said:is there a minimum current for a proper operation of an input pin?
i want to use the largest possible resistor in order to obtain the smallest possible current for a minimum power loss.
i'm using PIC16F84A
this is the circuit:
bmcculla said:If the port has pull up resistors swapping the switch and resistor will draw current (through the pulup and the external resistor to ground).
