This circuit is a Water Level Indicator With Anti-Corrosion Feature !!

In this circuit i used some wires with different lengths to detect the water level.

But to avoiding Electrolysis Corrosion we have to using AC voltage instead of DC voltage,

To do that i used IC NE555 to generate a low AC voltage. 

I explained that in this video: https://youtu.be/wrMyt4tC5oQ


Parts List:

IC NE555

Red LED (4pcs)

Green LED (4pcs)

Red LED (4pcs)

Yellow LED (6pcs)

Resistor 33K

Resistor 1.5K

Capacitor 100nF (9pcs)

Capacitor 1nF
