I have a question that I am curious about. I am designing an IoT device from my microcontroller. My question is how far can jumper wire (standard solid-core copper wire) go before it loses significant signal or power? The purpose is to drive a relay about half-way around my house. It isn't high frequency on/off, at most once per minute, so I'm thinking it won't pickup interference. The signal is +5V. Does thin jumper wire make the cut?
Edit: by popular demand, the current draw is 71.4 mA and the coil resistance is about 70 Ohms.
More Edit: Significant voltage drop would be probably more than 1.0 V, and ringing is acceptable, so long as it is not outside of this range.
