Hello everybody,
Today while I was testing some ICs. I used the logic probe to test them. One of the ICs was connected to LED and the LED was lighting (the output was high). I tested the output pin which is connected to the LED with the probe but it didn't read high. I tried it again when the output was low and it gave the right reading (Low). Can you help me in explaining that
and I need some information about this probe because I should submit a report tomorrow about it in addition to the explanation of the question above.
Thank u all
