Hi, very appreciate for the replies. Yes i am referring to the GPIO pins, I have assigned them properly and have tested the output, just not very sure as to how the input is applied. I want to make a water sensor using a magnet to activate the switches as the water level rises. I got the program to move from state to state when the assigned pins sees a GND, but the thing is I think the pins are overly sensitive. When i attatch a free standing wire to test the pins, the state switches just by touching them even with my fingers. Is there a way to avoid this?
Thanks
Greg
