Hi All ,
my pic circuit is working well , but i noticed something and need to know what does it mean ,
when i finished testing my circuit i removed it's positive terminal from the battery that mean my circuit will not run because there are no supply .
but
my circuit LED indicator still light up and i found out that's because i still connecting my photosensor to one of the input ports and it supply 1 to this port.
my question is :
how this positive signal goes from this port to supply all the circuit? , is it normal with pic circuits ?......or i have short in my circuit ?
