So I have an Arduino Nano that I think might have gone bad. The Vin and ground pins are shorting (I'm checking continuity with a multimeter). But it only shorts when:
- The Arduino has power
- The red lead of the multimeter is on ground and the black is on Vin (not the other way around)
I've tried checking with the leads both ways (red to ground as well as red to vin) while both on and off, and with two different multimeters, one of which is brand new. Completely at a loss for words because this isn't really how physics is supposed to work (continuity shouldn't depend on lead orientation from the multimeter or whether the circuit is powered, right?). Any insight would be appreciated. Do I have a bad board?
