Hello,
Im building a project that has 2 float switchs for measuring water depth. When both switchs are activated it switchs on a 12v pump (via mosfet) until the water drops below the lower float switch.
However im having an issue with the float switch.
I have everything on a picaxe experimenter board if i use the boards push buttons to simulate float switchs it works perfectly however as soon as i connect up the float switchs it becomes very unreliable.
Sometimes it works fine but most of the time it will only activate the pump for a brief moment and not for the full duration down to the bottom float switch.
Its like the bottom float switch isnt activating fully.
Is there a way to change how much activation the switch needs before the picaxe sees a 1 or 0
