Hi All,
What i'm trying to do:
I would like a led to light when i insert two probes into water, the 'probe circut' is powered by a 3.7v lithium ion battery and there is approx 800 microamps flowing when then probes are in the water.
Could you give me some help with a basic circut that will allow me to detect current flow in the 'probe circut' and then switch a led on please?
Kind regards,
Andrew
