Hi,
I'm in Haiti and I'm trying to build a simple level indicator for a water reservoir. The reservoir is about 9ft. deep, but will always have about 10" of water in the bottom.
I'm trying to make something that uses 5 or 6 wires of varying lengths extending into the reservoir in such a way that when I press a momentary switch a LED will come on if the tank has two feet of water or 2 LEDs will come on if the tank has 3ft of water, 3 LEDs if the tank has 5ft, 4 LEDS at 7ft and 5 LEDs at 8ft. I have a pretty good variety of resistors, a handful of 5mm Red LEDs, a push button NO switch and terminal(barrier strip) some perf board, 5 colors of #14 wire. I understand that the wires will deteriorate over time. Can someone jot a diagram on a napkin and take a picture of it for me?
Thanks so much,
Scott
