Im building a salinity probe using the arduino. The arduino outputs a constant 5 volts to a circuit of two resistors in a parallel circuit. one resistor is a variable resistor that changes based off of salt content.
My problem is that the anologRead is only outputting a value of 14. and only 14. it doesnt matter if its being supplied 5 volts or 3.3 or if i use A0 A1, A2, ect.
Need to see a diagram of your wiring, Fritzing only as a last resort. You can make a simple drawing with paper & pencil, take a picture with a camera or phone and attach it, look at the bottom of reply page for attachments.
