How do I wire a 4-pin power relay?
Two pins energize the coil and the other two are the switch contacts. Confirm the pin assignment on the relay label or datasheet before wiring, and size the load wiring for 20A.
Can I drive the coil directly from an Arduino pin?
A microcontroller pin usually cannot supply the coil current. Use a transistor or MOSFET driver stage and add a flyback diode across the coil to protect the driver from voltage spikes.
