But when I used a separate power supply for the lock and kept everything else the same it fixed my issue. So the freewheeling diode idea sounds great. I thought the relay module that I was using would have that covered though. Can I have some more specifics on what kind of diode I should use and where exactly in the circuit it should go? | |

Really the only other I/O devices that are connected are maybe 1-3 LEDs, push buttons, magnetic contact switches, or some microphone sensors. Can the current running through the 12v input of the voltage regulator(for the lock) be too high? | |
