I may have asked this question a long time ago but I can not find it here on this “new” site.
I have a Uno alone in a wooded field running some sensors and wired to some other Unos a few feet away. Serial communication. All is well. Independent battery power to all sensors groups (common grounds between all).
It has not happened yet but i am concerned about an animal chewing through wires and creating a short. I was wondering is I used a 1/8 watt 1 Ohm resistor off the VCC and / or GND will it blow in the event of a short circuit.
I fabricated a bunch to test out and get inconsistent results (some times a clean blow, some times the resistor will continue to leak about 1/2 voltage, sometimes no blow at all). I assume the cheep resistors I bought online are not made to good tollerances.
Is there a better way to accomplish what I am trying?
