Hello,
Theoretical question, I don't have drawings or any code, just trying to grasp the concept from my inexperienced perspective.
Supposing I have a device that has a RJ45 output and that when a certain condition is met the device sends anywhere from 5-24v DC through pin 1 with pin 2 being the ground, how can I determine that this is happening?
Since I don't know what the voltage will be, my first thought was a relay that I can connect to my Picaxe project that would make one of my pins high when the condition is met. Is this the right idea or is there a more efficient (or easier) way to accomplish this? If the relay is the way to go, would the little relays that techsupplies.co.uk sells be sufficient?
I've been trying to parse through and wrap my head around all the different info on measuring/regulating voltage, but I don't care about that, just looking for a boolean ON / OFF state status.
Thank you!
