they turn off... This is contrary to what you would think (or would want). In any event, you need a way to translate the high (3.3V) output of the GPIO pin to 0V for each input of the relay board. This is done using a 2.2kohm resistor...
But you don't have to wait for a storm to bring an electromagnet to life. A current is introduced, either from a battery or another source of electricity, and flows through the wire. This creates a magnetic field around the coiled wire, magnetizing the metal as if it were a permanent ...
Attach the wire to the relay with a female blade to the negative side, which is the last free terminal. Attach the dash side of the 16-gauge wire to the switch with a female blade terminal and mount the switch to the bottom of the dash. Run a ground wire on the other terminal of ...
