    its works like a switch but it use water as the switch. If the wire is contact with water, it will turn on the led.

    dear i dint get your point how the led will turn on when the wire touch with the water?

    The water will guide the electricity and thus works as a switch. But it seems that this will drain the battery quite quick. :-)

    But still nice project :-)

    Thank you for sharing nice project.

    You can add a "push" button on any side (or both on one 4 pin) to save battery drain. Whenever you press the button, you can check which leds will lit up.
