I want to design a LED indicator circuit so that it lights up when device is connected.
For example:
Phone --- connected to circuit --- connected to power source for charging = phone charging + LED ON.....
and........
Nothing connects to circuit --- circuit still connected to power source = LED off
What is a simple way to do this?
